At DisneyWorld the Christmas season officially starts on the Saturday after Thanksgiving. Next year that will be November 24.
Every November the parks and resorts are gradually transformed. Here's a general outline of what's happening this month.
Beginning immediately after the last Halloween party which was on Nov 1 this year they started decorating the parks and resorts for Christmas. The MK will be fully decorated by Nov 8 in time for the first Christmas party. The only exception is the big tree in Town Square which won't go up until after the parade is filmed during the first week end in December.
People have reported that the tree is up at the Studio. The Osborne Lights are up and due to be turned on this week also.
At Epcot the Candlelight Processional and Holiday Storytellers begin on the Saturday after Thanksgiving. There's also a gingergread house inside the Liberty Inn in the American Pavillion.
At the Grand Floridian the large gingerbread house is being assembled and should be finished by next week.
There will be trees, swags and decorations at all of the resorts which are installed throughout this month.
