I have been tracking the availability at 7 months and the BC 2BR are available starting after the first week in Jan so far this coming year. Jan through September availability is pretty good at most resorts except GF - that is a little tougher to get into. Oct to first week in Jan is a busy time for
DVC and thus at that time of year you might only be able to book at your home resort.
If you are looking to get the best deal then SSR is the best deal when factoring in price per point and yearly MF's. With that said we were in your shoes and ended up buying at AKV - we stayed on trip at SSR and although it is nice we did not care for the vibe or lack there of,.and you will be able to stay at most if not all DVC with some flexibility with travel times. If you want to get an idea of the resorts, besides reading here sometimes it is helpful to view some
youtube videos of that.
