Everything you describe has been happening for years at BWV and I don't see anyone there campaigning to get rid of the BW view. It will also be true of AKV, yet I think few (nobody) would favor combining the Savanna and Standard view categories.
SSR's size alone dictates that it will always be the last resort to fill. Disagree if you will but I don't think the entire concept should be disregarded simply because it will help those who want to book on 2-3 weeks' notice. If people want to go that badly, they will pay the price and accept a split stay. People willingly do it now, moving from one resort to the next--or one room class to the next--because they have no other options available.
Incidentally, I can think of one other very good reason to consider this proposal--the impact on other resort bookings at 7 months. Right now if I book SSR at 11 months, I have to live with the fact that my room may be in my preferred section of the resort--or it could be in the worst location possible. That fact alone is sufficient to drive people to attempt to book elsewhere at 7 months. Why fret over the possibility of being put in The Carousel or The Paddock if you can book AKV Savanna view at 7 months?
Now, if I KNEW 11 months out that I would absolutely have the room that I want (DTD view, golf course view, The Springs, etc.), it would have a dramatic impact on my desire to book elsewhere.
In my opinion, such a system would unquestionably increase the percenatage of SSR owners staying at their Home resort.
