Christmas decorations at the Walt Disney World Resort typically begin going up around the first of November. The decorations are gradually added at night and are for the most part complete at Magic Kingdom by the time of the first Mickey’s Very Merry Christmas Party, with the resorts and other parks completed by the day after Thanksgiving. The decorations usually start coming down about January 3.
The Disney resorts are all decorated for the holidays, as are the theme parks. Each theme park will have an enormous decorated Christmas tree and so will the Deluxe resort lobbies.
