Vero was an odd choice for a resort.... but basically I think they wanted something close to the parks that was beachfront... The main issue with Vero was, there isn't enough to do there... especially for a week... We love it, but how many meals are you going to eat at Wind and Waves... It isn't a surprise the second half of the property failed...
HHI didn't get built in the location they wanted initially... They ended up with some leftover plots in essence and hoped that the beach club would cut it... There's no restaurant, etc.
AUL I don't know well enough, but my understanding is it has location issues as well....
Then you run into the units themselves...
DVC units have various issues - especially with the price attached to point costs... Terrible mattresses, etc.
I think the "studio-heavy" nature of DVC also makes the off-property resorts more challenging... You might not mind a studio when you're spending the whole day with your family in the theme parks... When there's nothing to do but a boring pool, you might feel differently...
Given that dollars are finite even for a firm like DIS, I don't see them green lighting a DVC in Colorado over a new cruise ship for example....
