Carol is correct, the first two weeks of December are probably THE most popular times at
DVC, due to the low points, Christmas decorations are up and there's so much going on.
On top of that, BWV is probably THE most popular resort for this time of year.
I would think your best bet would be one of the larger resorts, OKW or SSR since they have so many more units.
SSR might be a good choice since they will be adding new units as construction continues, thus creating more availability.
What is your home resort? If it's SSR, you should book there NOW, before the 7-month window opens. Or if you need to waitlist, you should be near the top of the listing.
In all honesty, I think your chances of getting ALL of your BWV preferences is zero. You might get parts of some, but the chance of getting everything is probably zero.
