The Haunted Mansion at the Walt Disney World Resort

It's an attraction that has spawned multiple movies and merchandise and is found in a different part of every park around the world.  The Haunted Mansion tells different stories of it's owners and their afterlife.  In Disneyland it's located in New Orleans Square, it's in Liberty Square in Disney World, Fantasyland in Tokyo Disneyland and Frontierland in Disneyland Paris.  All but the last follow the storyline of the master of the house hanging himself and lead you through the now haunted home.  However the attraction in Disneyland Paris has a different storyline that ties in with the area surrounding it.  In the Paris version it is the daughter of a wealthy land owner that haunts the house, having waited for her love who was killed by her father (unknown by her) to come to her.  Part of the house is destroyed by the same natural force that destroyed the town in Big Thunder Mountain Railroad.

Each attraction has a facade that reflects the area it is housed in and follow the same basic layout.  You enter a stretching room that may actually be an elevator depending on which park you are in that gives you an introduction from the ghost host himself.  A door appears out of nowhere and you then follow the path to where you will load into your doom buggy.  You will soon find yourself being led through the house and a witness to many haunted scenes such as a ghost ball.  And if you keep an eye out you may even spot a hidden Mickey.
