This Way

At the Park, there are many doors leading to the utilidoore, which contains the winding tunnels under Magic Kingdom. One particular door is near the Teacups, and the cast members affectionately refer to it as "The Rabbit Hole." This is partially due to its location, but also due to the fact that there's simply a door and no other markings, so we kind of have to look for the stairs.

Someone helpfully inscribed directions pointing to the staircase. Someone Else, of course, had to add their description.
