Accounting Policies [Abstract]
Principles of Combination and Consolidation	Principles of Combination and Consolidation Subsequent to January 3, 2017, the unaudited condensed combined consolidated financial statements include the accounts of the Company, our wholly owned subsidiaries and entities in which we have a controlling financial interest, including variable interest entities (“VIEs”) where we are the primary beneficiary. The historical unaudited condensed combined consolidated financial statements through January 3, 2017 represent the financial position and results of operations of entities held by us after the spin-off that had historically been under common control of the Parent. The historical unaudited condensed combined consolidated financial statements were prepared on a carve-out basis and reflect significant assumptions and allocations. The unaudited condensed combined consolidated financial statements reflect our historical financial position, results of operations and cash flows, in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP. In our opinion, the accompanying unaudited condensed combined consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All significant intercompany transactions and balances within the financial statements have been eliminated. These financial statements should be read in conjunction with the audited combined consolidated financial statements and notes thereto for the year ended December 31, 2016 included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 2, 2017, and “Financial Statements and Supplementary Data,” included in Exhibit 99.2 to our Current Report on Form 8-K, filed with the SEC on May 5, 2017.
Allocations	Allocations Through January 3, 2017, the historical condensed combined consolidated statements of comprehensive income included allocations of corporate general and administrative expenses from Hilton on the basis of financial and operating metrics that Hilton historically used to allocate resources and evaluate performance against its strategic objectives. We considered the basis on which expenses were allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by us during the historical periods presented. However, the allocations may not include all of the actual expenses that would have been incurred by us and may not reflect our condensed combined consolidated results of operations, financial position and cash flows had we been a stand-alone company during the historical periods presented. Actual costs that might have been incurred had we been a stand-alone company would depend on a number of factors, including the chosen organizational structure, what functions we might have performed ourselves or outsourced and strategic decisions we might have made in areas such as information technology and infrastructure. Following the spin-off, we performed these functions using our own resources or purchased services. For an interim period, some of these functions will continue to be provided by Hilton under our transition services agreement (“TSA”).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Interim results are not necessarily indicative of full year performance.
Reclassifications	Reclassifications Certain line items on the condensed combined consolidated balance sheets as of December 31, 2016 have been reclassified to conform to the current period presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606). This ASU supersedes the revenue recognition requirements in Revenue Recognition (Topic 605) and requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequent to ASU 2014-09, the FASB has issued several related ASUs. The provisions of ASU 2014-09 and the related ASUs are effective January 2018 and are to be applied retrospectively or using a modified retrospective approach; early adoption is permitted. Based on our assessment to-date, we do not expect the timing of recognition and amount of revenues from room, food and beverage, and other revenue to change. We also do not expect sales of real estate that involve cash with few contingencies to be materially affected; however, the new standard may allow for earlier revenue recognition for sales of real estate where we have continuing involvement. We expect to adopt the new ASUs using the modified retrospective approach and do not anticipate that this will result in a material cumulative effect adjustment to retained earnings as of January 1, 2018.
