On OP's "far and wide" question, I think DVC has very limited ability to expand geographically.
Forget the economics of building and selling a timeshare resort in this economic environment -- DVC's problems are much more fundamental than that. DVC's BIG problem is one of differentiation -- or in this case, the inability to differentiate.
If you can't offer something
unique, the competition becomes one based on price, and DVC will lose that fight every time to much larger systems with lower cost structures.
DVC works best where DVC properties offer a unique advantage over competitive products. At WDW, there is no question that DVC has a clear advantage -- they are ONsite, and they are Disney resorts. Those two factors carry an enormous variety of advantages which make DVC worth its price for many.
IMHO, DVC still works
some at
Disneyland in California. Certainly not as well as WDW, but at least it is Disney and is as onsite as you can get at Disneyland. I think it's weak -- particularly when compared to the competition in the timeshare field -- but that's just my opinion.
At the overseas Disney theme parks, I think DVC could enjoy a marketable advantage...with the caveat that I am not familiar with the laws in those countries regarding timeshares (which could make a DVC offering impossible). Again, the nexus is a
Disney theme park.
Without the Disney theme park, I just don't see any rationale for a Disney timeshare.
To me, VB, HHI, and Aulani -- although each lovely resorts in their own way -- really don't belong because there is no
there there. Great resorts, but what's the point of a
Disney resort? Especially when you can buy competitive products for $1 on eBay, rather than tens of thousands of dollars for DVC!
