The issue facing Disney isn't one of where we DVC members want to stay. The real question is if there's an off-site location where Disney Vacation Development (DVD) can profitably sell DVC ownerships to new buyers and existing members.
At WDW, Disney already owns prime land. But, off-site, desirable land for timeshare resorts is rare and expensive.
At WDW, Disney has the ability to market to prospective buyers at Disney's resorts and theme parks. But, off-site, Disney would have to deal with high marketing costs, including costly premiums to get prospective buyers to attend "tours" (as the timeshare industry tends to call their sales pitches).
At WDW, Disney's brand name is very valuable. But, off-site, Disney's brand names may attract some prospective buyers, but may actually turn off other prospective buyers; in any case, Disney's brand is much less valuable off-site than at WDW.
At WDW, Disney has a history of selling timeshare inventory fairly quickly. And Disney can easily rent out unsold, undeclared inventory through CRO. But, off-site, if inventory sells more slowly (as was the case at VB and HHI), Disney faces the carrying costs on unsold inventory. And off-site, depending on the location, it could be more difficult to rent out unsold, undeclared inventory.
At WDW, Disney has the best competitive position against other timeshare developers. But, off-site, companies like Marriott, Starwood, Wyndham, Hyatt, and Hilton are likely to have a competitive advantage over Disney.
Now, having said all that, I actually think we may see the DVC brand on off-site timeshare resorts despite Disney's experience with VB and HHI. If Disney can find investors to put up the capital and minimize Disney's risk, then Disney and the investors could leverage the DVC brand. The timeshare business and the lodging business in general have changed since VB and HHI. Disney has a respected brand; the timeshare industry is more respectable; and there's now a large existing base of DVC members to whom off-site DVC resorts can be marketed as a starting point.
