Yes, I agree that is a new incentive. The other thread was talking about 2 different items in the member clubhouse. The first one was this line:
"In the spirit of the holiday season, Disney Vacation Club is, for the first time ever, offering Walt Disney World Theme Park admission to Members who purchase an additional Ownership Interest equal to 50 or more Vacation Points"
This is the incentive that you are referring to.
The other second item that was being talked about in the other thread was this line further down in the clubhouse where it is talking about what is coming up in the Winter Issue of Vacation Magic:
"All this, plus the announcement of a long-awaited Member perk"
Most are hoping this new perk that is going to be announced in the Winter Issue of Vacation magic is some type of AP ticket discount.
