Guests meander through a haunted maze entrance to arrive at Haunted Mansion 2013, an event that the organizers bill as the area's "scariest and sexiest halloween party." Hip hop, pop, and EDM hits pulse through the space as revelers pose for a professional photographer, woo even the most intimidating monsters with their dancing skills, or visit one of the six bars.
