You can only use the 11 month window at a resort where you
A) own, and
B) have enough points, AT THAT RESORT, to make the reservation.
If you own at two or more resorts, there are lots of strategies you can create to use more than your annual allotment at a resort.
For example, if you had 150 points at BWV and 150 at WVL, and wanted to book something for 151 - 300 points at BWV at the 11 month window you could use this years 150 points and borrow 150 from BWV from next year. Then next year, you could stay at WVL, using the same strategy
You could also bank points at one location one year, and then the next year make a reservation for up to 450 points by using the 150 banked points, 150 current year points, and 150 borrowed points.
You could also try to swap points once during the year with someone who had the opposite situation.
There are many ways to be creative when you own contracts at more than one resort.
