As for booking with SSR points, I have been an owner with all of my points at SSR since 2004

. Last Easter, which is one of the buiser times of the year, we stayed in the THV and did 9 days

.
I called right at the 11 month window and got all 8 nights on the first call. If you are or have SSR points and call at the 11 month window you shouldn't have a problem. If you call at the 7 month window I agree with the other posters, I think flexibility is the key

. In any case, we LOVED the Treehouses, and would stay there again in a heartbeat!!
