I'm not a lawyer -- not even a "jailhouse lawyer" -- but I agree with Brian on this. The language I've always heard is something like "...as long as the resort is a member of the Club, owners will be able to use points at all Club resorts."
And, not for nothin', creating a "new club" would hurt members of the new club more than it would hurt members of the old club. If members can't use their points at X resort, then obviously owners of X resort - being a member of a different club -- can't use their points at the ten resorts currently in
DVC #1. So they could possibly create a new "club" for VGF and Poly, but those owners would not be able to use their points anywhere else.
Who would buy that? Nobody in their right mind.
The other thought I'd offer here is that IF DVC did impose "resale = home resort only" restrictions, CAN YOU IMAGINE how devalued a direct purchase would become at the instant of closing???
A direct purchaser would be buying something that had virtually no value on resale.
Frankly, a purchase in that context would be a "natural selection" fail...one of those "There's a sucker born every minute" kinds of things.
