DISNEYLAND's Haunted Mansion sat empty for several years while Walt Disney pondered what would go inside it.
One of the first concepts was a walk-through attraction designed by Imagineer Rolly Crump called "Museum of the Weird".
Guests would walk through the attraction and encounter strange "antiques" and other oddities that defied imagination.
It never quite worked out, however. Park operations felt that a walk through attraction wouldn't be practical in a busy theme park like DISNEYLAND. Many of the ideas eventually became part of the Haunted Mansion, though guests would experience the attraction in a ride instead of on foot.
