If you are unable to use those points by 11/30/02, you will lose them.
Vacation points in a holding account (because a
DVC reservation was cancelled 30 days or less before arrival) can be used for a stay at a DVC resort as long as you book the reservation 60 days or less before you arrival date. You cannot use those points for anything at all after 11/30/02.
You can also use those points for an exchange through the Disney Collection, the Adventurer Collection, the Conceirge Collection or the World Passport Collection as long as you book it before 9/30/02. (You cannot book non-DVC options AND travel during the last 60 days of your use year). FWIW, all of these options cost more than 11 points. You'd have to borrow more points from 2002 to take advantage of them.
As already stated by DebbieB, holding points cannot be banked or borrowed.
Your options for these 11 points are quite limited. Subject to availability, you could book one weeknight in a studio at VB, HHI, OKW or a standard view at BWV. You could rent/transfer them to another member, give them away, or try to rent one night as described above. That's about it. I think I'd just resign myself to losing them and consider it a cost of getting those last minute days at BCV.
Enjoy your trip. It sounds like fun!
