I agree with HBC, we have also had very good luck with that week in Dec. Wonderful time to be at WDW.
BWV & BCV are excellent choices for their location to Epcot and MGM and all the holiday festivites (Candlelight Processional, WS Christmas shows, Osborne Lights, etc). We love staying in this area all year long, but it is even more convenient during certain times of the year, and the holidays are definitely one of them. But have you also considered VWL? All the resorts are decorated very nicely for the holidays but none of them are like WL/VWL at Christmas. These resorts are the stuff Norman Rockwell Christmas paintings could be based on, LOL!
Have a wonderful trip!
