Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Operations	Business and Operations Gaming and Leisure Properties, Inc. ("GLPI") is a self-administered and self-managed Pennsylvania real estate investment trust ("REIT"). GLPI (together with its subsidiaries, the "Company") was incorporated on February 13, 2013, as a wholly-owned subsidiary of Penn National Gaming, Inc. ("Penn"). On November 1, 2013, Penn contributed to GLPI, through a series of internal corporate restructurings, substantially all of the assets and liabilities associated with Penn’s real property interests and real estate development business, as well as the assets and liabilities of Hollywood Casino Baton Rouge and Hollywood Casino Perryville, which are referred to as the "TRS Properties," and then spun-off GLPI to holders of Penn's common and preferred stock in a tax-free distribution (the "Spin-Off"). The Company elected on its United States ("U.S.") federal income tax return for its taxable year beginning on January 1, 2014 to be treated as a REIT and the Company, together with an indirectly wholly-owned subsidiary of the Company, GLP Holdings, Inc., jointly elected to treat each of GLP Holdings, Inc., Louisiana Casino Cruises, Inc. (d/b/a Hollywood Casino Baton Rouge) and Penn Cecil Maryland, Inc. (d/b/a Hollywood Casino Perryville) as a "taxable REIT subsidiary" ("TRS") effective on the first day of the first taxable year of GLPI as a REIT. As a result of the Spin-Off, GLPI owns substantially all of Penn’s former real property assets and leases back most of those assets to Penn for use by its subsidiaries, under a master lease, a triple-net operating lease with an initial term of 15 years with no purchase option, followed by four 5 year renewal options (exercisable by Penn) on the same terms and conditions (the "Penn Master Lease"), and GLPI also owns and operates the TRS Properties through an indirect wholly-owned subsidiary, GLP Holdings, Inc. GLPI’s primary business consists of acquiring, financing, and owning real estate property to be leased to gaming operators in triple-net lease arrangements. As of March 31, 2016, GLPI’s portfolio consisted of 21 gaming and related facilities, including the TRS Properties, the real property associated with 18 gaming and related facilities operated by Penn and the real property associated with the Casino Queen in East St. Louis, Illinois. These facilities are geographically diversified across 12 states. GLPI expects to grow its portfolio by pursuing opportunities to acquire additional gaming facilities to lease to gaming operators under prudent terms, including its July 2015 announcement of the proposed acquisition of substantially all of the real estate assets of Pinnacle Entertainment, Inc. ("Pinnacle") and its December 2015 announcement of the resolution of the previously disclosed litigation with The Meadows Racetrack and Casino (the "Meadows") and entry into an amended purchase agreement with Cannery Casino Resorts LLC, the owner of the Meadows. Furthermore, in March 2016, the Company announced it had entered into an agreement to sell the entities holding the Meadows gaming and racing licenses and operating assets to Pinnacle. GLPI will lease the Pinnacle and the Meadows real property assets to Pinnacle under separate triple-net leases. The Pinnacle transaction is expected to close during April 2016, while both transactions involving the Meadows are expected to close during the late third quarter of 2016. However, we cannot predict the actual dates on which the transactions will be completed because each transaction is subject to conditions beyond such parties' control. On July 20, 2015, GLPI, Gold Merger Sub, LLC, a direct, wholly owned subsidiary of GLPI ("Merger Sub"), and Pinnacle entered into a merger agreement (as it may be amended from time to time, the "Merger Agreement") providing for the merger of Pinnacle with and into Merger Sub, with Merger Sub surviving the merger as a wholly owned subsidiary of GLPI (the "Merger"). Following the consummation of the Merger, GLPI will own all of Pinnacle’s real property assets, other than Pinnacle’s Belterra Park property and excess land at certain locations. In order to effect the acquisition of Pinnacle’s real property assets (other than the Belterra Park property and excess land at certain locations), prior to the Merger, Pinnacle will cause certain assets relating to its operating business to be transferred to, and liabilities relating thereto to be assumed by a newly formed wholly owned subsidiary of Pinnacle ("OpCo"). Immediately following the separation, Pinnacle will distribute to Pinnacle’s stockholders all of the issued and outstanding shares of common stock of OpCo owning Pinnacle’s operating assets and certain other specified assets. Then, upon satisfaction or waiver of the conditions to closing in the Merger Agreement on the closing date, Pinnacle will merge with and into Merger Sub, as described in more detail in the joint proxy statement/prospectus filed with a Registration Statement on Form S-4 (No. 333-206649) initially filed by GLPI with the Securities and Exchange Commission on December 23, 2015 and declared effective on February 16, 2016 (the "Joint Proxy Statement/Prospectus"). Merger Sub, as the surviving company in the Merger, will then own substantially all of Pinnacle’s real estate assets that were retained or transferred to Pinnacle in the separation and will lease those assets back to OpCo pursuant to a triple-net 35 year (including extension renewals) master lease agreement (the "Pinnacle Master Lease Agreement) substantially in the form attached as Exhibit B to the Merger Agreement. A wholly-owned subsidiary of OpCo would operate the leased gaming facilities as a tenant under the Pinnacle Master Lease Agreement. At the effective time of the Merger, each share of Pinnacle common stock issued and outstanding immediately prior to the effective time of the Merger will be converted into 0.85 shares of a share of GLPI common stock, with cash paid in lieu of the issuance of fractional shares of GLPI common stock. The exchange ratio will not be adjusted to reflect changes in the price of GLPI common stock or the price of Pinnacle common stock occurring prior to the completion of the Merger. The obligations of GLPI and Pinnacle to effect the Merger are subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement. Substantially all of the conditions to closing the Merger, including each company's stockholders' approval and gaming regulatory approvals have been satisfied and the Company expects the Merger to close at the end of April 2016. Upon completion of the Merger, the current directors and officers of GLPI are expected to continue in their current positions, other than as may be publicly announced by GLPI in the normal course of business. Approval by GLPI shareholders and Pinnacle stockholders was obtained at separate special meetings held on March 15, 2016. At the GLPI special meeting, GLPI shareholders voted on (i) a proposal to approve the issuance of GLPI common stock to Pinnacle stockholders in the Merger and (ii) a proposal to approve one or more adjournments of the meeting to another date, time or place, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the issuance of shares of GLPI common stock to Pinnacle stockholders in the Merger. At the Pinnacle special meeting, Pinnacle stockholders voted on (i) a proposal to adopt the Merger Agreement, (ii) an advisory (non-binding) proposal to approve certain compensation that may be paid or become payable to the named executive officers of Pinnacle in connection with the Merger, and (iii) a proposal to approve one or more adjournments of the meeting to another date, time or place, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the Merger and the other transactions contemplated by the Merger Agreement. The Joint Proxy Statement/Prospectus describes the foregoing proposals in more detail, as well as other matters contemplated in connection with the proposed Merger. On March 25, 2016, the Company and Pinnacle entered into the First Amendment to the Merger Agreement which extended the closing date of the Merger to April 30, 2016. The Merger Agreement may be terminated, subject to certain exceptions, prior to the effective time of the Merger by either GLPI or Pinnacle under certain conditions, including if the Merger has not been consummated on or before April 30, 2016, subject to one two-month extension by GLPI, at the election of GLPI, if the only conditions not satisfied at such time related to regulatory and other government approvals.
