I would think early Dec would be hard due to low points at that time, but you never know until you try. There are been posts recently about people getting one at the 7mo window and even a waitlist coming through. If you have a chance anywhere at the 7 mo window its at OKW! I would book at backup just in case. Maybe reserve something at your home resort at 11 mo and then switch over at 7. That way you won't be without anything.
