My choice, without a doubt would be VWL. This resort at Christmas is like looking at a perfect Christmas card. Between the decor of the resort, the fantastic christmas tree, the wonderful and huge firepladce, the smells, the cozy nooks and seating areas, etc., this resort just screams "old fashioned Christmas".
All the WDW resorts are decorated very nicely for the holidays to varying degrees but WL/VWL is one of the very best, imo.
