LOL, that was the speculation of a wildly popular podcast last year by someone most would consider a well-informed Disney expert.
And yes, Disney could sell Aulani or any other
DVC resort. It's part of the rules, and it's in your paperwork. And I wouldn't be surprised to see DVC sell any of the off-sites. VB in particular is problematic IMO. Disney is holding a whole lot of bags of Aulani, and DVC has made less predictable decisions than that, IMO. Depends on how much Disney is willing to keep committing to these properties to run them to something close to Disney standards. The pool heat thread is not a good sign for that.
