Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements presented herein include 100 percent of our assets, liabilities, revenues, expenses and cash flows as well as all entities in which we have a controlling financial interest. In our opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All material intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect our financial position, results of operations and cash flows as prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP have been omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Although we believe the disclosures made are adequate to prevent information presented from being misleading, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto as of and for the year ended December 31, 2019, included in our Annual Report on Form 10-K filed with the SEC on March 2, 2020. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and, accordingly, ultimate results could differ from those estimates. Interim results are not necessarily indicative of full year performance. COVID-19 The novel coronavirus (“COVID-19”) pandemic continues to significantly negatively impact the hospitality, travel and leisure industries due to various mandates and orders to close non-essential businesses, impose travel restrictions, require “stay-at-home” and/or self-quarantine, and require similar actions. Such restrictions and directives have resulted in cancellations and significant reductions in travel around the world, as well as the negative global economic conditions resulting from the impact of the COVID-19 pandemic. As a result of the reduction in travel, during the first quarter of 2020 we closed substantially all of our resorts and sales centers. In addition, in response to the impact of COVID-19, we have taken a variety of actions to ensure the continuity of our business and operations, including workforce furlough, implementing temporary salary reductions for the remaining active employees primarily during the second quarter of 2020, eliminating all discretionary spending, and reducing our planned investment in new inventory by approximately $200 million. Further, during the first quarter of 2020, we drew down on the availability under our credit facility as a precautionary measure to ensure liquidity for a sustained period and on May 8, 2020, we amended our Credit Agreement which amended certain terms of the credit facilities (“Senior Secured Credit Facilities”) to provide us with both near-term and long-term flexibility with respect to satisfying certain negative and financial covenant ratios as may be needed due to the ongoing and uncertain future impact of the COVID-19 pandemic on our business and operations. See Note 11: Debt and Non-recourse debt for additional actions taken with respect to our financial flexibility. Recently, we announced a workforce reduction plan that will affect approximately 1,600 team members in order to better align our workforce with the Company’s needs in light of the current environment. In addition, approximately 2,000 of our team members remain furloughed. Prior to re-opening our resorts and sales centers, we introduced the HGV Enhanced Care Guidelines, designed to provide owners, guests and team members with the highest level of cleaning protocols and safety standards recommended by the Center for Disease Control and Prevention and cleaning solutions approved by the Environmental Protection Agency in response to the COVID-19 pandemic. Along with providing personal protective equipment to team members, these Enhanced Care Guidelines include low-touch arrivals and departures, frequent and thorough cleaning, reduction of paper items, reduced capacity for our pool decks and fitness centers, and new technologies. While operations were suspended, essential resort personnel worked diligently maintaining the resorts for a safe re-opening. Annual deep cleanings, typically scheduled during slower seasons, were moved up and completed, allowing the resorts to be in top shape when owners and guests arrive. Beginning in May 2020, various states and counties started to allow gradual relaxation of restrictions on activities and a resumption of businesses. In response, we began a phased reopening of resorts and resumption of our business activities during the second quarter of 2020, but under new operating guidelines and with safety measures. As of September 30, 2020, we have over three quarters of our resorts and sales centers open and currently operating however, many of our resorts and sales centers are operating with significant capacity constraints and subject to various safety measures. In addition, ongoing strict travel and other restrictions in regions and locations where we have a significant number of resorts and concentration of units, in particular, Hawaii and New York, are significantly impacting consumer demand for our resorts in those areas. While we plan to continue to reopen our resorts and resume our business as conditions permit, the pandemic continues to be unprecedented and rapidly changing, and has unknown duration and severity. Further, various state and local government officials may issue new or revised orders that are different than current ones under which we are operating. Accordingly, there remains significant uncertainty as to the degree of impact and duration of the conditions stemming from the ongoing pandemic on our revenues, net income and other operating results, as well as our business and operations generally. Any significantly extended duration or worsening of the conditions associated with the pandemic may adversely impact our liquidity in the longer term, including our ability to finance our day-to-day business and operations, and may adversely affect our ability to comply with our maintenance and financial covenants and ratios under our debt obligations notwithstanding the recent amendments discussed above. However, we believe that prior to triggering an event of default, if any, in connection with the financial covenants under our debt agreements we would be able to reach an agreement with our lenders to amend such covenants in advance of any potential default. Additionally, as a result of the ongoing COVID-19 pandemic, we are performing a review over certain of our long-lived assets in order to determine our optimal strategic direction with regards to these assets. These assets include undeveloped parcels of land and certain unallocated infrastructure costs related to future phases of existing resorts. The result of this review could have a material impact on the carrying value of certain assets, which could result in non-cash impairments.
Accounts Receivable and Allowance for Credit Losses	Accounts Receivable and Allowance for Credit Losses Accounts receivable primarily consists of trade receivables and is reported at the customers’ outstanding balances, less any allowance for credit losses. The expected credit losses are measured using an expected-loss model that reflects the risk of loss and considers the losses expected over the outstanding period of the receivable.
Cloud Computing Arrangements	Cloud Computing Arrangements We capitalize certain costs associated with cloud computing arrangements (“CCAs”). These costs are included in Other assets in our condensed consolidated balance sheets and are expensed in the same line as the hosting arrangement in our condensed consolidated statements of operations using the straight-line method over the assets’ estimated useful lives, which is generally three to five years. We review the CCAs for impairment when circumstances indicate that their carrying amounts may not be recoverable. If the carrying value of an asset group is not recoverable, we recognize an impairment loss for the excess of carrying value over the fair value in our condensed consolidated statements of operations.
Derivative Instruments	Derivative Instruments We use derivative instruments as part of our overall strategy to manage our exposure to market risks primarily associated with fluctuations in interest rates and do not use derivatives for trading or speculative purposes. We record the derivative instrument at fair value either as an asset or liability. We assess the effectiveness of our hedging instruments quarterly and record changes in fair value in accumulated other comprehensive income (“AOCI”) for the effective portion of the hedge and record the ineffectiveness of a hedge immediately in earnings in our condensed consolidated statements of operations. We release the derivative’s gain or loss from AOCI to match the timing of the underlying hedged items’ effect on earnings.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Adopted Accounting Standards On January 1, 2020, we adopted Accounting Standards Update (ASU) No. 2016-13, (“ASU 2016-13”), Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASC 326”), using the modified retrospective approach. The new standard requires that expected credit losses relating to financial assets measured on an amortized cost basis are measured using an expected-loss model, replacing the current incurred-loss model, and recorded through an allowance for credit losses. The adoption of ASU 2016-13 did not have a material impact on our condensed consolidated financial statements and related disclosures and no cumulative adjustment was recorded primarily as our timeshare financing receivables are recorded net of an allowance that is calculated in accordance with ASC 606, Revenue from Contracts with Customers. On January 1, 2020, we adopted ASU 2018-15 (“ASU 2018-15”), Customer’s Accounting Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on recognizing implementation costs incurred in a cloud computing arrangement that is a service contract with that for implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. This ASU has been adopted using the retrospective approach. Accordingly, previously reported financial information has been restated to reflect the application of the new standard to the comparative periods presented. The adoption of ASU 2018-15 did not have a material impact on our condensed consolidated financial statements. In March 2020, the SEC issued a final rule, Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities, which simplifies the disclosure requirements related to registered securities under Rule 3-10 of Regulation S-X. The rule replaces the requirement for a parent entity to provide detailed disclosures with regard to guarantors of registered debt offerings within the footnotes to the consolidated financial statements. Under the final rule, a parent entity is required to present summarized financial information of the issuers’ and guarantors’ balance sheets and statements of operations on a consolidated basis. It also requires qualitative disclosures with respect to information about guarantors and the terms and conditions of guarantees. These disclosures may be provided outside the footnotes to the Company’s consolidated financial statements. We early adopted the reporting requirements of the rule in the second quarter of 2020 and elected to provide these disclosures in Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations. Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU 2019-12 (“ASU 2019-12”), Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 is intended to simplify various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and which also clarifies and amends existing guidance to improve consistent application. The provisions of this ASU are effective for reporting periods after December 15, 2020. We are currently evaluating the effect that this ASU will have on our condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04 (“ASU 2020-04”), Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the effect that this ASU will have on our condensed consolidated financial statements.
