This question comes from Rebbecca: Can you tell me when Christmas decorations go up at WDW? We’ll be there mid-November.
Rebbecca: Decorations go up in the parks first. In fact, work has been underway on the castle and in Hollywood Studios for the Osborne Lights for weeks now. Light displays such as these go up first and then, right after Halloween, the parks are completely decked out. You can expect the parks to be finished by November 8th, which is when the first Mickey’s Very Merry Christmas Party begins and when the Osborne lights are turned on. The main difference you’ll see from November to December is that the Christmas tree in Town Square is placed there from another location in the Magic Kingdom after the taping of the Christmas parade in early December.
Resorts vary. Last year, for example, Pop Century, the Grand Floridian (including the gingerbread house) and the Polynesian were decorated by November 18th, but the Epcot area resorts weren’t finished until November 24th, so you may miss out on some resort displays.
Thanks for your question and I hope this helps!
