For ambience and atmosphere, I would vote WL and VWL. To stay at, BLT -- MK view --- castle lights, holiday wishes on the TV,,,,, ah, only about 235 days to go.
Best resort is your home resort reserved 11 months out because for Christmas week you are unlikely to get anything else at 7 months out. Ours are BWV and AKV and have done Christmas at both. Both were fine. NYE, AKL Jambo had an outstanding band and party going in the lobby.
