And they have actively promoted Riviera as a separate resort, as DVC, etc.
The Coronado Tower has been promoted as part of CSR, and the phrase DVC has never been mentioned once by Disney promo.
As I've said elsewhere: Either CSR isn't going to be DVC, or they are doing a terrible job promoting it given that it would need to start sales EXACTLY when Riviera does. Worst hype ever.
In all likelihood, CSR and the reno will be used to amp up splitting most convention traffic between CSR and the two convention centers in the Epcot area. That leaves them open to tear down the Contemporary Convention Center, which either needs a huge refurb or to be gone. It's not in prime conference shape, especially compared to the other three halls. But it is prime property for a free-standing DVC.
