After Disney's death in December 1966, the project evolved significantly; the Museum of the Weird restaurant idea was abandoned. The Imagineers objected to a walk-through attraction's low capacity, going so far as suggesting building two identical attractions to accommodate twice as many guests. A solution appeared with the development of the Omnimover system for Adventure Thru Inner Space. Renamed the '"Doom Buggy", the system's continuous chain of semi-enclosed vehicles offered high capacity. The cars could be set to rotate in any direction at any point, allowing the Imagineers to control what guests saw and heard throughout the show. And because each car held from one to three people, it was a convenient way to divide guests into smaller groups — a better fit with the story of people wandering "alone" through a haunted house.
