Again, you're simply wrong.
Marriott Vacations Worldwide (VAC stock,) is the timeshare company under which Marriott Vacation Club-branded timeshares and several others fall. As the developer/manager, MVW owns and manages all timeshare intervals which have not been sold to owners or conveyed to any of the Trusts that have been established by the companies which come under the MVW umbrella (which Trusts consist of the underlying intervals that support sales.) MVW also owns rights to the common areas of every Marriott-branded timeshare. Prior to the change in corporate structure that separated the timeshare segment to the new MVW company, Marriott Vacation Club-branded timeshares came under the Marriott, Int'l (MAR stock) hotel company's umbrella.
In neither corporate structure have the timeshares ever been franchised to outside owners or managers. First MAR and then VAC managed the properties and that continues to this day.
What you're describing routinely happens in the majority of hotel company structures, that the individual hotels are franchised under separate ownership with each individual franchise owner paying a fee to MAR for licensing/name branding and inclusion in MAR's reservation system as well as other items. VAC also pays a fee to MAR for licensing/branding/IT systems but not as franchisers.
You're correct that Disney-branded hotels come under the Disney umbrella, which makes them an outlier in the industry, but you're absolutely wrong in claiming that Marriott timeshares are or ever have been franchised. Like DVC, MVW as the developer owns unsold/unconveyed intervals until they're purchased/conveyed, and MVW manages every Marriott-branded timeshare. Perhaps it's you who should be reading the investor filings for MAR and VAC, before making any more claims that are simply false.
