It seems that Disney's timeshare development subsidiary, Disney Vacation Development (DVD), has decided to concentrate strictly on WDW on-site
DVC resorts.
DVD enjoys all sorts of business advantages at WDW that lead to the profitable sale of DVC memberships:
- The ability to market to on-site resort guests and park guests who are likely to like Disney (else why would they be at WDW?)
- The use of land that Walt Disney acquired for an average of $300 per acre
- The ability sell at a high volume, so that resorts sell out in as little as a year, thus reducing the carrying costs of unsold inventory
And Disney enjoys all sorts of indirect financial benefits from DVC members who return year after year to spend money at Disney parks, shops, and restaurants.
By the way, there's also the management fee (approx. 2% of the total operating budget) that Disney gets for being the management company at any DVC resort, but that has nothing to do with being on-site or off-site.
In comparison, at off-site locations, Disney faces serious marketing challenges, high land costs for prime sites, and, in the case of HHI and VB, a long, slow sell-out, where it's likely that marketing and carrying costs chewed up the profit.
