Marriott Vacations Worldwide Corporation, a leading global vacation company, offers vacation ownership, exchange, rental, resort and property management services. As of 2023-end, the company had more than 120 resorts and 700,000 owners and members in a diverse portfolio of seven vacation ownership brands. It also has exchange networks and membership programs in more than 3,200 resorts in 90 countries.

Marriott Vacations’ business is operated under two major segments — Vacation Ownership (accounting for 94% of total revenues in 2023) and Exchange & Third-Party Management (6%).

The Vacation Ownership Exchange segment generates the major chunk of its revenues from four sources — selling vacation ownership products, managing vacation ownership resorts, clubs and owners’ associations; financing consumer purchases of vacation ownership products; and renting vacation ownership inventory. Their resorts typically offer a blend of home comforts, including spacious accommodations with one, two, and three-bedroom options, living and dining areas, kitchens, and laundry facilities, along with resort amenities such as swimming pools, dining venues, convenience stores, fitness centers, spas, and tailored sports and recreational facilities tailored to each resort's unique setting.

The company’s Exchange & Third-Party Management segment revenues are fee-based and are derived from membership, exchange and rental transactions, property and owners’ association management, and other related products and services.

In 2018, Marriott Vacations announced the completion of its merger with ILG, Inc., a renowned provider of vacation experiences. Marriott Vacations closed the deal by paying roughly $4.6 billion. On the completion of the acquisition, Marriott Vacation’s board of directors included two members from ILG’s board.
