I agree with the 11 month window. We already own at SSR. Our next move would be to BCV (Three young DCs to enjoy the pool, and Epcot is my favorite.) If for some reason we could not get BCV, then we would look at BWV then OKW.
Again, the draw is the 11month window. Nothing else. You could simply add those points to your existing points, but then you do not get the advantage of the 11 month window.
Just my 2cents
