Accounting Policies [Abstract]
Nature of Operations	The Interim Consolidated Financial Statements present the results of operations, financial position and cash flows of Marriott Vacations Worldwide Corporation (referred to in this report as (i) “we,” “us,” “Marriott Vacations Worldwide,” “MVW,” or the “Company,” which includes our consolidated subsidiaries except where the context of the reference is to a single corporate entity, or (ii) “MVWC,” which shall refer only to Marriott Vacations Worldwide Corporation, without its consolidated subsidiaries). In order to make this report easier to read, we refer throughout to (i) our Interim Consolidated Financial Statements as our “Financial Statements,” (ii) our Interim Consolidated Statements of Income as our “Income Statements,” (iii) our Interim Consolidated Balance Sheets as our “Balance Sheets,” and (iv) our Interim Consolidated Statements of Cash Flows as our “Cash Flows.” In addition, references throughout to numbered “Footnotes” refer to the numbered Notes in the Interim Condensed Notes to Consolidated Financial Statements, unless otherwise noted. Capitalized terms used and not specifically defined herein have the same meanings given those terms in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Annual Report”). We also use certain other terms that are defined within these Financial Statements.
Principles of Consolidation	The Financial Statements presented herein and discussed below include 100% of the assets, liabilities, revenues, expenses, and cash flows of Marriott Vacations Worldwide, all entities in which Marriott Vacations Worldwide has a controlling voting interest (“subsidiaries”), and variable interest entities (“VIEs”) for which Marriott Vacations Worldwide is the primary beneficiary in accordance with consolidation accounting guidance. References in these Financial Statements to net income attributable to common stockholders and MVW stockholders’ equity do not include noncontrolling interests, which represent the outside ownership of our consolidated non-wholly owned entities and are reported separately. Intercompany accounts and transactions between consolidated entities have been eliminated in consolidation. These Financial Statements reflect our financial position, results of operations, and cash flows as prepared in conformity with United States Generally Accepted Accounting Principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Such estimates include, but are not limited to, revenue recognition, cost of vacation ownership products, inventory valuation, goodwill and intangibles valuation, accounting for acquired vacation ownership notes receivable, vacation ownership notes receivable reserves, income taxes, and loss contingencies. The uncertainties in the broader macroeconomic environment, including inflation outpacing wage growth, continuing high interest rates, mixed economic indicators and increased global insecurity, have made it more challenging to make these estimates. Actual results could differ from our estimates, and such differences may be material. In our opinion, our Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position, the results of our operations, and cash flows for the periods presented. Interim results may not be indicative of fiscal year performance because of, among other reasons, general macroeconomic conditions, including inflationary pressures and seasonal and short-term variations. These Financial Statements have not been audited. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP. Although we believe our footnote disclosures are adequate to make the information presented not misleading, the Financial Statements in this report should be read in conjunction with the consolidated financial statements and notes thereto in our 2023 Annual Report. We refer to the business and brands that we acquired in the acquisition of ILG, LLC, formerly known as ILG, Inc. (“ILG”), in 2018 (the “ILG Acquisition”) as “Legacy-ILG.” We refer to the business we conducted prior to the ILG Acquisition and the associated brands as “Legacy-MVW.” We refer to the business and brand that we acquired in the acquisition of Welk Hospitality Group, Inc. (“Welk”) in 2021 (the “Welk Acquisition”) as “Legacy-Welk.” During 2023, we rebranded all Legacy-Welk resorts as Hyatt Vacation Club resorts. Additionally, we use the term “Marriott Vacation Ownership” to refer to our Marriott-, Sheraton-, and Westin-brands and the term “Hyatt Vacation Ownership” to refer to our Hyatt-brands. We have reclassified certain prior year amounts to conform with our current year presentation.
