If you're hoping to go in early December, you should plan on booking sooner than 6 months out and I wouldn't get your hopes up for BCV/BWV/BLT/VWL for that time frame for a 10-night trip. That has become the BUSIEST time at DVC and many, many people reported this year that they had to keep their reservations at their home resorts because the other resorts had zero availability at seven months out.
If you think this time period might be when you typically will visit Disney (especially for a long trip such as 10 nights) you may want to rethink your home resort (and also make it a point to book earlier than your 3-6 month time frame) if you don't want to stay at SSR during that time of year.
it is way to busy for us at this time of year as a family. An adults only weekend trip would be in cards if the opportunity and availability to do so was there. I was using that as an example because the calculator that I was using did not have the 2013 points entered in it yet and we booked into the Beach Club Villas for next May though our Disney Vacation Expert.
