According to the DVC member guidelines, if a DVC member accepts $$$ for the points, their "guests" are not entitled to DVC benefits/perks, which includes pool hopping. However, most report that this rule is not widely followed or enforced. If your resort ID says "DVC Member", you will probably be allowed to pool hop. For the time you plan to go, it is unlikely that there will be any capacity problems, but as Gary mentioned, you should call over to the resort ahead of time to make sure.
That said, I hope that you already have your BWV reservation or have a back up plan. The dates you listed are very popular with DVC members and my understanding was that the first part of December booked up very quickly. Some members reported that they are on the waitlist for this time. I don't know if there is still a waitlist and of course, sometimes you just get lucky.
The first week in December is a great time to go. Hope you have a wonderful trip!
