"Though not as intricately constructed as a Shakespearean play, a story exists. In fact, Imagineering legend and Disneyland veteran Tony Baxter believes that, in the end, combining the seemingly divergent work of Marc Davis and Claude Coats inadvertently gave the Haunted Mansion a fairly solid three-act structure.
"In Act One, which begins slowly and ominously in the Foyer, guests anticipate the appearance of the happy haunts, and experience poltergeist activity and unseen spirits.
"Madame Leota provides the curtain that separates Act One and Act Two. The medium conjures up the spirits and encourages them to materialize, which they promptly do in the swinging wake in the Grand Hall and the Attic.
"The descent from the attic window into the Graveyard takes guests into Act Three, in which they are completely surrounded by the ghosts who are enjoying the manic intensity of a graveyard jamboree. Finally, one of three Hitchhiking Ghosts materializes beside the guests in their Doom Buggy before the exit."— Jason Surrell, the Haunted Mansion: from the Magic Kingdom to the Movies
And just like that, T-Bax provides one of the most “structureless” attractions with a crystal-clear Experiential Story.
