Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Business Operations	1. Organization and Business Operations Organization and General TPG Pace Holdings Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on February 14, 2017 (“Inception”). The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The Company’s sponsor is TPG Pace II Sponsor, LLC, a Cayman Islands limited liability company (the “Sponsor”), which is an affiliate of TPG Global, LLC. On June 9, 2019, the Company formed two new wholly-owned subsidiaries, New Pace LLC and Pace Merger Sub LLC, both Delaware limited liability companies, in contemplation of the Proposed Business Combination, as defined below in “Proposed Business Combination”. All activity for the period from Inception to June 30, 2019 relates to the Company’s formation and the initial public offering of units, each consisting of one of the Company’s Class A ordinary shares and one-third of one warrant to purchase one Class A ordinary share (the “Public Offering”), the identification and evaluation of prospective acquisition targets for a Business Combination and the entry into the Transaction Agreement (as defined below) in connection with the Proposed Business Combination. The Company will not generate operating revenues prior to the completion of the Business Combination and will generate non-operating income in the form of interest income on Permitted Investments (as defined below) from the proceeds derived from the Public Offering. The Company has selected December 31st as its fiscal year end. Going Concern Pursuant to the provisions of the Company’s amended and restated memorandum and articles of association, it currently has until September 30, 2019 to complete an initial Business Combination. The Company is seeking shareholder approval to amend its amended and restated memorandum and articles of association and trust agreement governing the trust account with Continental Stock Transfer and Trust Company, acting as trustee (the “Trust Account”) to extend such date to December 31, 2019. If the Company does not complete an initial Business Combination by September 30, 2019 or by December 31, 2019, if the Company receives shareholder approval to amend its amended and restated memorandum and articles of association and the trust agreement to extend such date to December 31, 2019, the Company will (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem all of the Class A ordinary shares issued as part of the units in the Public Offering at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest, net of taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish the shareholder rights of owners of Class A ordinary shares (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution, including Trust Account assets, will be less than the initial public offering price per unit in the Public Offering. In addition, if the Company fails to complete its Business Combination by September 30, 2019 or by December 31, 2019 if the Company receives shareholder approval to amend its amended and restated memorandum and articles of association and trust agreement to extend such date to December 31, 2019, there will be no redemption rights or liquidating distributions with respect to warrants to purchase the Company’s Class A ordinary shares, which will expire worthless. At June 30, 2019, the Company had current liabilities of $4,283,400 and negative working capital of $3,591,303 largely due to amounts owed for professional fees associated with the Proposed Business Combination. As discussed below, the Company has the ability to use annually up to $750,000 of interest earned from the Trust Account to fund working capital. The Company’s ability to continue as a going concern is dependent upon its ability to consummate a Business Combination or have access to sufficient interest income from the Trust Account to fund expenses and negative working capital balances. If there is insufficient interest income available to pay such amounts in full or if a Business Combination does not occur, the Company will need to obtain additional funds to meet its liabilities. Management’s potential options for obtaining additional working capital, to the extent needed, include requesting loans from the Sponsor or affiliates of the Sponsor, or certain of the Company’s executive officers or directors. Additional funds could also be raised through a private offering of debt or equity. There can be no assurance that the Company will be able to raise such funds if they are needed. In addition, the Company’s successful completion of the Proposed Business Combination is contingent on customary closing conditions, including, but not limited to, approval by the Company’s shareholders, approval by Accel’s shareholders, expiration or termination of the waiting period under the Hart-Scott Rodino Antitrust Improvements Act and approval by the Pennsylvania Gaming Control Board. The uncertainty regarding the need for and ability to obtain such funding raises substantial doubt about the Company’s ability to continue as a going concern. This mandatory liquidation and subsequent dissolution requirement raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties about the Company’s ability to continue as a going concern. Financing The registration statement for the Company’s Public Offering was declared effective by the United States Securities and Exchange Commission (the “SEC”) on June 27, 2017. The Public Offering closed on June 30, 2017 (the “Close Date”). The Sponsor purchased an aggregate of 7,333,333 warrants at a purchase price of $1.50 per warrant, or $11,000,000 in the aggregate, in a private placement on the Close Date (the “Private Placement”). The warrants are included in additional paid-in capital at the balance sheet. The Company intends to finance a Business Combination with proceeds from its $450,000,000 Public Offering (see Note 3) and $11,000,000 Private Placement (see Note 4). The proposed financing for the Proposed Business Combination is discussed below under “Proposed Business Combination.” At the Close Date, proceeds of $450,000,000, net of underwriting discounts of $9,000,000 and funds designated for operational use of $2,000,000, were deposited in the Trust Account as described below. The Trust Account On January 2, 2018, funds held in the Trust Account were invested in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations (collectively, “Permitted Investments”). Funds will remain in the Trust Account except for the withdrawal of interest earned on the funds that may be released to the Company to fund working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes. The proceeds from the Public Offering will not be released from the Trust Account until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance and timing of the Company’s obligation to redeem 100% of the public shares if the Company does not complete the Business Combination within the designated period, including extensions. Of the remaining proceeds of $2,000,000 held outside the Trust Account, $300,000 was used to repay the loan from the Sponsor, with the remainder used to pay offering costs, business, legal and accounting due diligence on prospective acquisitions, listing fees and continuing general and administrative expenses. Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating a Business Combination with (or acquisition of) a target business. As used herein, the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the Company signing a definitive agreement. As discussed below, the Company entered into a definitive agreement for a proposed Business Combination and will provide the public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares either (i) in connection with a shareholder meeting to approve the Business Combination or (ii) by means of a tender offer. Each public shareholder may elect to redeem their shares irrespective of whether they vote for or against the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the Trust Account is initially anticipated to be approximately $10.00 per public share. The per-share amount the Company will distribute to investors who properly redeem their shares will not be reduced by any deferred underwriting commissions payable to underwriters. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval under the law or stock exchange listing requirements. If the Company seeks shareholder approval, it will complete its Business Combination only if a majority of the outstanding Class A ordinary shares voted are voted in favor of the Business Combination. However, in no event will the Company redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 after payment of the deferred underwriting commission. In such an instance, the Company would not proceed with the redemption of its public shares and the related Business Combination, and instead may search for an alternate Business Combination. The Company’s Sponsor and five independent directors (collectively, “Initial Shareholders”) and the Company’s officers and directors have entered into a letter agreement with the Company, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to their Founder Shares (as defined in Note 4) if we fail to complete a Business Combination by September 30, 2019 or by December 31, 2019 if the Company receives shareholder approval to amend its amended and restated memorandum and articles of association and trust agreement to extend such date to December 31, 2019. The underwriters have agreed to waive their rights to any deferred underwriting commission held in the Trust Account in the event the Company does not complete the Business Combination and those amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s public shares. If the Company fails to complete the Business Combination, the redemption of the Company’s public shares will reduce the book value of the shares held by the Initial Shareholders, who will be the only remaining shareholders after such redemptions. If the Company holds a shareholder vote or there is a tender offer for shares in connection with a Business Combination, a public shareholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to fund its working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes. As a result, such ordinary shares are recorded at their redemption amount and classified as temporary equity on the balance sheet, in accordance with ASC 480, “Distinguishing Liabilities from Equity.” Proposed Business Combination On June 13, 2019, the Company entered into a Transaction Agreement (as it may be amended from time to time, the “Transaction Agreement”) with each of the person set forth on Schedule I thereto (collectively, the “Sellers”) and David Ruttenberg and John S. Bakalar (as successor to Gordon Rubenstein) (each in their capacity as shareholder representative, together the “Shareholder Representatives”) pursuant to which (i) the Company will acquire, directly or indirectly, all of the issued or outstanding shares of common stock and preferred stock of Accel Entertainment, Inc., an Illinois corporation (“Accel”) by the Sellers (the “Stock Purchase”); (ii) following the closing of the Stock Purchase, Accel will merge with and into New Pace LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Company (“NewCo”), with NewCo surviving such merger (the “Merger”, and together with the other transactions contemplated by the Transaction Agreement, the “Proposed Business Combination”). Accel is a gaming service provider located in the United States and operates approximately 8,000 video game terminals in more than 1,700 locations. Pursuant to the Transaction Agreement, at the closing of the Stock Purchase, holders of Accel’s stock will receive a mix of consideration comprised of (a) cash consideration equal to the number of Accel shares for which such holder makes an election to receive cash (a “Cash Election”) multiplied by $177 per share (the “Purchase Price”) and (b) share consideration comprised of New Parent Class A-1 Stock equal to the number of Accel shares for which such holder does not make a Cash Election multiplied by the Purchase Price divided by approximately $10.22 per share (such price per share to be determined as set forth in the Transaction Agreement), subject to pro rata adjustment in the event that holders of Accel’s stock elect more than $350,000,000 in cash in the aggregate. In addition, holders of Accel’s stock who roll more than 30% of their shares of Accel common stock into the new structure will receive a pro-rata share (based upon the number of shares rolled in excess of the 30% threshold) of (a) 2,444,444 of our New Accel Warrants (as defined below) and (b) 3,000,000 shares of our Class A-2 Common Stock (as defined below) subject to vesting conditions that will be set forth in a restricted stock agreement. The New Parent Class A-1 Stock is expected to be listed on the NYSE upon consummation of the Proposed Business Combination. On July 22, 2019, pursuant to Section 8.13 of the Transaction Agreement, the Company, the Sellers and the Shareholder Representatives entered into Amendment No. 1 to the Transaction Agreement (the “Amendment”), which provides for certain administrative amendments to the Transaction Agreement. On July 23, 2019, in connection with the Transaction Agreement, as amended by the Amendment, and pursuant to a drag-along agreement, dated as of June 13, 2019 (the “Drag-Along Agreement”), by and among the Company and the persons named as Dragging Shareholders thereto (the “Dragging Shareholders”), the Dragging Shareholders issued a written notice to Accel and certain shareholders of Accel, pursuant to which they agreed to exercise their right to cause each Accel shareholder who has not entered into the Transaction Agreement to deliver a joinder to the Transaction Agreement, pursuant to which such shareholder will be bound by all of the terms and conditions of the Transaction Agreement (as modified by such joinder). For further discussion of the Proposed Business Combination, the Transaction Agreement and the Amendment, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Proposed Business Combination.”	1. Organization and Business Operations Organization and General TPG Pace Holdings Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on February 14, 2017 (“Inception”). The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The Company’s sponsor is TPG Pace II Sponsor, LLC, a Cayman Islands limited liability company (the “Sponsor”), which is an affiliate of TPG Global, LLC. All activity for the period from Inception to December 31, 2018 relates to the Company’s formation and the initial public offering of units, each consisting of one of the Company’s Class A ordinary shares (“Public Shares”) and one-third of one warrant to purchase one Class A ordinary share (the “Public Offering”), and the identification and evaluation of prospective acquisition targets for a Business Combination. The Company will not generate operating revenues prior to the completion of the Business Combination and will generate non-operating income in the form of interest income on Permitted Investments (as defined below) from the proceeds derived from the Public Offering. The Company has selected December 31st as its fiscal year end. Going Concern If the Company does not complete an initial Business Combination within 24 months from June 30, 2017 (the “Close Date”), or 27 months from the Close Date if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months of the Close Date, the Company will (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem all of the Class A ordinary shares issued as part of the units in the Public Offering at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account with Continental Stock Transfer and Trust Company acting as trustee (the “Trust Account”), including interest, net of taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish the shareholder rights of owners of Class A ordinary shares (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

This mandatory liquidation and subsequent dissolution requirement raises substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties about the Company’s ability to continue as a going concern. Financing The registration statement for the Company’s Public Offering was declared effective by the United States Securities and Exchange Commission (the “SEC”) on June 27, 2017. The Public Offering closed on the Close Date. The Sponsor purchased an aggregate of 7,333,333 warrants at a purchase price of $1.50 per warrant, or $11,000,000 in the aggregate, in a private placement on the Close Date (the “Private Placement”). The warrants are included in additional paid-in capital at the balance sheet. The Company intends to finance a Business Combination with proceeds from its $450,000,000 Public Offering (see Note 3) and $11,000,000 Private Placement (see Note 4). At the Close Date, proceeds of $450,000,000, net of underwriting discounts of $9,000,000 and funds designated for operational use of $2,000,000, were deposited in the Trust Account as described below. The Trust Account Prior to January 2018, funds held in the Trust Account were not invested and were held in a non-interest bearing account. On January 2, 2018, funds held in the Trust Account were invested in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations (collectively, “Permitted Investments”). Funds will remain in the Trust Account except for the withdrawal of interest earned on the funds that may be released to the Company to fund working capital requirements, subject to an annual limit of $750,000, and/or to pay taxes. The proceeds from the Public Offering will not be released from the Trust Account until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance and timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete the Business Combination within 24 months from the Close Date, or 27 months from the Close Date if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months of the Close Date and (iii) the redemption of all of the Company’s Public Shares if it is unable to complete the Business Combination within 24 months from the Close Date, or 27 months from the Close Date if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months of the Close Date, subject to applicable law. Of the remaining proceeds of $2,000,000 held outside the Trust Account, $300,000 was used to repay the loan from the Sponsor, with the remainder available to pay offering costs, business, legal and accounting due diligence on prospective acquisitions, listing fees and continuing general and administrative expenses.

However, if the Initial Shareholders acquire Public Shares after the Close Date, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within the allotted 24-month time period, or 27 months from the Close Date if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months of the Close Date.
