I've maintained recently, and have yet to see evidence to the contrary, that for at least the next 10 years, BCV will be increasingly difficult at 7 months for this reason. Anyone buying BCV right now is doing it solely to get home resort. No one is buying BCV for run-of-network points. (Same is true of BWV, although it is slightly larger so that might impact.)
BCV is too expensive to be buying for any other purpose but home resort. And as fewer people can get it at 7 months, it probably magnifies the effect.
If you want to stay at BCV regularly in the next 20 years, you own BCV. No substitute. Yes, you'll pay a premium. But it's do that, or stay elsewhere.
