I actually would consider choosing whichever resort you'd like to stay at that you will most likely NOT get at 7 months. So, you book the hardest to get at 11 months and you will still most likely be able to get SSR, OKW, AKV and maybe even PVB (it may get harder once sold out). You just have to make sure you have enough points to stay at the resort with the highest points requirement. Of the ones you listed, PVB will take at least 50% more points to stay at than OKW.
We bought BWV because we want to stay there the most and it's hard to get the standard studios, but many would argue that because of the 2042 end date that's not the smart choice. Still worth it to us to stay there and enabled us to "get in" with minimum points. PVB and VGF were off my list due to the point requirements and I've just removed them from my mind as options. Ha ha. If we purchase a 2nd resort, it will likely be BLT because I don't know if we'd be able to get a standard studio without the 11 mo window. So, in the end, we would minimally be able to stay at BLT, BWV, SSR, OKW, AKV and - if we're lucky and flexible - elsewhere. I'm OK with not staying at BCV because I consider BWV an "equal" and I feel like I'm ok with either BRV or CCV, so hopefully we can get into one or the other at some point. If so, that pretty much covers everything we're looking to accomplish. And with the addition of a 2nd contract, we may actually have enough points sometime to stay PVB or VGF if the opportunity presented itself and that would just be a bonus I'm not counting on.
