This year marks the tenth anniversary of Haunted Mansion Holiday at Disneyland park, but there was one celebration you might not have known about. Each year, some very different teams from across Disneyland Resort gather for a very special project: the Haunted Mansion Holiday gingerbread house. Cast members from teams like Operations, Engineering, Creative Development and Food and Beverage all work together to bring this spooky but tasty creation to life. In this video, we learn how they do it and what they do to mark their special reunion each year.
