In true winter fashion, the Great Hall set will be outfitted with decorations used for the actual Yule Ball scene in the movie, including Christmas trees and other seasonal ornaments. Hogwarts guests can also expect to find wintry decorations across all the other sets, just as they appeared in the films. The iconic Gryffindor Common Room will get its own cozy Christmas transformation, and the castle itself will be blanketed in snow.
The magical Christmas dinner and tour will take place on the evenings of December 10th through 12th, and it’ll cost about $315 per person. Tickets can be purchased starting on September 15th at 10:00 AM from the Warner Bros. Studio Tour website. The event itself will run from 6:00 PM to midnight.
