IMO all the parks have a different type of Christmas feeling, some areas of each park are more decorated than others. Main Street at MK, World Showcase at Epcot, Hollywood Blvd at MGM, and Camp Minnie and Mickey at AK. MGM has a sort of nostalgic feeling, I like it the best, Epcot I like about equally, with Christmas around the world, and the candlelight procession. It's a bit more elegent. MK is a nice Disney Christmas. My least favorite would be AK. The Epcot resorts, and MK resorts also have great decorations.
