Yes, there are three prominent hotels located on Walt Disney World property in Florida that are owned and operated by Marriott International. These are the Walt Disney World Swan, the Walt Disney World Dolphin, and the Walt Disney World Swan Reserve. While they sit directly in the heart of the Epcot resort area and are designed by the same legendary architect (Michael Graves) who worked on Disney-owned hotels, they are Marriott-managed properties. Specifically, the Swan is part of the Westin brand, while the Dolphin and Swan Reserve fall under the Sheraton and Autograph Collection brands, respectively. Because they are not "Disney-owned," guests can use Marriott Bonvoy points to book stays, which is a major advantage for business travelers. However, because of a long-standing partnership, guests at these hotels receive almost all the same perks as those at Disney-owned "Deluxe" resorts, including Early Theme Park Entry, Extended Evening Hours, and free Disney bus and boat transportation. This unique "hybrid" arrangement makes them some of the most popular choices for travelers who want Disney convenience combined with the familiarity of a major global hotel loyalty program.
