BW has been VERY difficult to get this year, even for us owners.( It was hard last year within the 7 month window.) We booked at the 11 month window for Nov. We have tried to add rooms but nothing is available, and the 7 month window hasn't even opened up yet! It has NOT always been this difficult. I guess it depends on when you want to go. If there is still room on the waitlist, I would suggest going on it. We had success with it last year. ( Rooms came through about 6 weeks before we left, we already had OKW rooms and we just switched over.)
Good Luck
