Balou3...
I know it's not a 2-bedroom, but I just wanted to encourage you that the waitlist does work! I've recently had a number of days come through for a Preferred Studio at BWV in early December.
Like you, we own at VWL, and I made reservations there at the 11-month window. In early May, when the 7-month window opened up, I started calling MS on a daily basis (thanks to advice from this board). Some days BWV was available, and some days were not. After 11 days of calling every morning, my BWV schedule was a fragmented mess. It looked something like this:
12/1-12/4 - Confirmed
12/5-12/6 - Waitlist
12/7 - Confirmed
12/8-12/11 - Waitlist
Fortunately, I had enough points to keep my reservation at VWL while waiting for BWV to come through.
Within a week, everything but 12/5 came through. Since I did get 10 out of 11, I cancelled the VWL reservation, so that hopefully someone trying to get in there could. I plan on making a cash reservation for 12/5 as a backup, in case the waitlist does not come through.
I agree with "spiceycat"...check with MS and see if your waitlist is for the entire time or daily.
Good luck!
