I think that both BWV and BCV are great resorts and it's why they are so often booked. I don't see them doing a tear down and re-build. If they did that, they lose a lot of inventory during this time period which means they lose money. My guess is they offer creative "extensions" or even new contracts but give current owners first opportunity. You never want to give the impression of not appreciating your current clients/owners. Perhaps they take a portion of these two and build vertically or take a section of the resorts and build vertical with a re-design. But a complete tear down? I just don't see it.
When speaking of Crescent Lake I think it's the best location of all resorts for so many people, especially with the way Hollywood Studios has expanded and Epcot with the festivals, etc.
What has always surprised me is the fact they allowed Marriott to have Dolphin and Swan and then add the new Tower to those two as well. That is/was PRIME location for Disney to add
DVC or retail locations that are pure Disney owned. I've read some of the history of the building of the two and the concern for lack of convention space, etc. but to me these two hotels are not very pleasing aesthetically at all. Now, I've stayed in them with Marriott points, especially when I get into Orlando late and want a one night stay prior to my WDW reservation beginning.
In truth, I think we all have our favorites and our own version of the best location, best resort, etc. etc. I will fully admit it's hard for me take my bias out of any opinion I have.
I guess all I really have to add to this, is I don't think they'll do a rebuild/tear down of the Crescent Lake locations. If anything, I'd love to see CBR go through a massive upgrade and change. It's a great location and I like the idea of the theme.
All this aside, to me I think Disney needs to find a way to add young fans of Disney again. As a whole, I think the newest generations aren't growing up with "Disney" like they did in the 60s, 70s, 80s and even the 90s. A lot of failed movies, failed choices and lack of original content is hurting. I also think Disney hasn't taken advantage of the classic movies to theme around as much as they could.
But that's an entirely different topic.
