Let's just look at two things we've seen already regarding DVC that have disappointed some.
1) SAB being closed - this really upset some BCV owners, but as
@Sandisw explained in detail, Disney basically has the right to do it, and with the NBA "leaks" yesterday, it makes sense that SAB would be closed.
2) and just today Jambo House - I'm know there are DVC owners who love those Value studios at Jambo and there are folks who love Jambo for other reasons, but DVC has confirmed
Like I said -- no matter what your affinity status with Disney is -- if you go in with a very open mind and are super flexible, you should be fine. Disappointed is different that devastated, but I'm convinced everybody will feel these changes. Also FWIW, I haven't heard of DVC Members being treated any differently than "cash" resort guests.
Again, I want to emphasize things can change and will change quickly.
