Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates The accompanying unaudited consolidated condensed financial statements of Caesars have been prepared under the rules and regulations of the Securities and Exchange Commission applicable for interim periods, and therefore, do not include all information and footnotes necessary for complete financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”). The results for the interim periods reflect all adjustments (consisting primarily of normal recurring adjustments) that management considers necessary for a fair presentation of financial position, results of operations, and cash flows. The results of operations for our interim periods are not necessarily indicative of the results of operations that may be achieved for the entire 2019 fiscal year. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities. Management believes the accounting estimates are appropriate and reasonably determined. Actual amounts could differ from those estimates.
Consolidation of Subsidiaries and Variable Interest Entities	Consolidation of Subsidiaries and Variable Interest Entities Our consolidated financial statements include the accounts of Caesars Entertainment and its subsidiaries after elimination of all intercompany accounts and transactions. We consolidate all subsidiaries in which we have a controlling financial interest and VIEs for which we or one of our consolidated subsidiaries is the primary beneficiary. Control generally equates to ownership percentage, whereby (i) affiliates that are more than 50% owned are consolidated; (ii) investments in affiliates of 50% or less but greater than 20% are generally accounted for using the equity method where we have determined that we have significant influence over the entities; and (iii) investments in affiliates of 20% or less are generally accounted for using the cost method. We review our investments for VIE consideration if a reconsideration event occurs to determine if the investment continues to qualify as a VIE. If we determine an investment no longer qualifies as a VIE, a gain or loss may be recognized upon deconsolidation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements The Financial Accounting Standards Board (the “FASB”) issued the following authoritative guidance amending the FASB Accounting Standards Codification (“ASC”). In 2019, we adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), and all related amendments (see Note 7). Additionally, we adopted ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) (see Note 14). The following ASUs were not effective as of September 30, 2019: Previously Disclosed Collaborative Arrangements - ASU 2018-18: Amended guidance makes targeted improvements to GAAP for collaborative arrangements including: (i) clarifying that certain transactions between collaborative arrangement participants should be accounted for as revenue under ASC 606 when the collaborative arrangement participant is a customer in the context of a unit of account, (ii) adding unit-of-account guidance in ASC 808 to align with the guidance in ASC 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of ASC 606, and (iii) requiring that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under ASC 606 is precluded if the collaborative arrangement participant is not a customer. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The amendments should be applied retrospectively to the date of initial application of ASC 606. An entity may elect to apply the amendments in this ASU retrospectively either to all contracts or only to contracts that are not completed at the date of initial application of ASC 606. An entity should disclose its election. An entity may elect to apply the practical expedient for contract modifications that is permitted for entities using the modified retrospective transition method in ASC 606. We are currently assessing the effect the adoption of this standard will have on our financial statements. Intangibles - Goodwill and Other - Internal-Use Software - ASU 2018-15: Amended guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The accounting for the service element of a hosting arrangement that is a service contract is not affected. The amendments in this update are effective for public entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently assessing the effect the adoption of this standard will have on our financial statements. Fair Value Measurement - ASU 2018-13: Amended guidance modifies fair value measurement disclosure requirements including (i) removing certain disclosure requirements such as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) modifying certain disclosure requirements, and (iii) adding certain disclosure requirements such as changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period. The amendments in this update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently assessing the effect the adoption of this standard will have on our financial statements. Financial Instruments - Credit Losses - ASU 2016-13 (amended through May 2019): Amended guidance replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables and any other financial assets not excluded from the scope that have the contractual right to receive cash. Amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. An entity will apply the amendments in this ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The effect of a prospective transition approach is to maintain the same amortized cost basis before and after the effective date of this ASU. We are currently assessing the effect the adoption of this standard will have on our financial statements. In February 2016, the FASB issued a new standard related to leases, ASU 2016-02, Leases (Topic 842) (“ASC 842”). We adopted the standard effective January 1, 2019, using the retrospective approach applied as of the beginning of the period of adoption. The Company elected to utilize the transition guidance within the new standard that permits us to (i) continue to report under legacy lease accounting guidance for comparative periods consistent with previously issued financial statements; and (ii) carryforward our prior conclusions about lease identification, lease classification, and initial direct costs. The most significant effects of adopting the new standard relate to the recognition of right-of-use (“ROU”) assets and liabilities for leases classified as operating leases when the Company is the lessee in the arrangement. Adopting the new standard did not affect our accounting related to leases when the Company is the lessor in the arrangement.
Leases	We assess whether an arrangement is or contains a lease at the inception of the agreement. ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term using an appropriate incremental borrowing rate, which is consistent with interest rates of similar financing arrangements based on the information available at the commencement date. Upon adoption, our ROU assets were also adjusted to include any prepaid lease payments and were reduced by any previously accrued lease liabilities. The terms of our leases used to determine the ROU asset and lease liability take into account options to extend when it is reasonably certain that we will exercise those options. Lease expense is recognized on a straight-line basis over the lease term. Additionally, we have elected the short-term lease measurement and recognition exemption and do not establish ROU assets or lease liabilities for operating leases with terms of 12 months or less.
Segment Reporting	We view each property as an operating segment and aggregate such properties into three regionally-focused reportable segments: (i) Las Vegas, (ii) Other U.S. and (iii) All Other, which is consistent with how we manage the business. The results of each reportable segment presented below are consistent with the way management assesses these results and allocates resources, which is a consolidated view that adjusts for the effect of certain transactions between reportable segments within Caesars. We recast previously reported segment amounts to conform to the way management assesses results and allocates resources for the current year. Net revenues are presented disaggregated by category for contract revenues separate from other revenues by segment. “All Other” includes managed, international and other properties as well as parent and other adjustments to reconcile to consolidated Caesars results.
