Beachangel:
You'll have no problem at all booking your 2-br at the 11 month window. I called 11 months out for the busiest time of the year (X-mas, New Year) and everything was available..even GVs. I secured a standard studio. It is my belief that not many of the DVC members call so much in advance. probably the DIS members are the ones that do call 11 months out, but out of the whole cake, we are only a small piece.
Make your reservations. You will absolutely love BWV. Guaranteed.
