The week Sammie was looking for is the coveted Adventure weeks of December when point counts are lowest but demand is highest.
It notoriously books solid within opening windows and we see switching at the 7 month window. What I find interesting is that nothing was left at SSR, even though they have added inventory since the 11 month window opened for the resort. Meanwhile things are opening at the other resorts. Sounds as if SSR owners booked and then didn't desire a change more than other resort owners. (Or owners in general booking SSR and sticking with it.)
My biggest concern has been that SSR loses its "stink of ugliness" in the owner rep department and availability suddenly becomes tight. I'd rather be able to have a choice of rooms when I check-in than have to take whatever's left.
