What's different about Haunted Mansion Holiday compared to the regular Haunted Mansion?

Is there a height requirement for Haunted Mansion Holiday?

Lightning Lane reservations for Haunted Mansion Holiday sell out quickly once the overlay season gets busy, so book one early in the day if you want to skip the standby line.

Do not rush past the ballroom scene partway through the ride: the gingerbread display there changes design every year and is one of the most detailed parts of the overlay.
