As eva says, the answer is both. But there's a catch - isn't there always, LOL?
At 11 months prior to your desired check out date, you have 120 points worth of "home resort booking advantage" at both resorts. You do not have 240 points of home resort booking advantage at one of the two.
Let's say you want to stay at BCV and the desired reservation requires 200 points. Prior to 7 months ahead of check out, you'd have to borrow 80 points from your next BCV use year to complete your BCV reservation. You cannot use the OKW points at BCV until the 7 month window opens. As an alternative, if there is still availability at BCV for your dates when the 7 month window opens, you could use use the OKW points to complete your reservation.
HTH.
