My THEORY on this (and it's just a theory), so please be gentle.
When Disney first built OKW, most people bought in because of the concept of DVC, and not so much the theming. Yes, the fact that it was/still is a beautiful resort with lots of great amenities helped a lot, but people were more into the idea of Disney's implementation of a timeshare on Disney property. As time went on, owners started to love their resort with a passion, and OKW & DVC really took off.
Disney then needed to expand DVC, so they added on to existing resorts, namely BWV, VWL & BCV. Now, you had a whole different breed of prospective owners. They were tapping into folks who have already stayed at these resorts and really loved them. People wo already had fond memories of the place, and perhaps had started some family traditions. Now theming & location & everything else that is agued about here became a lot more important, and contributed more to the decision making process than before with OKW.
Now along comes SSR. Even though SSR is built on the old DI property, it is pretty much brand new. There was no Saratoga Springs Inn, no Saratoga Springs Lodge. The majority of the people who are buying into SSR never stayed there before. Some have bought in without even seeing it first! So I think (key word is think), that we are going back to the OKW days where people are buying more into the DVC concept & not so much the SSR theme. nd it appears that Disney is marketing it that way too. So yes, there are a lot of SSR owners who are buying just to get into the system. Some of them might already have a love for one of the other resorts, but are not aware that you can still buy into them via resale or wait list. They may think that SSR (or AKV) is their only choice. BUT, just like OKW, SSR is a beautiful resort, and as moe & more people stay there, we are seeing that it is starting to get it's own band of rabid followers.
