Hanna's Haunted Acres gets spines shivering and blood curdling with six fright-filled attractions. Fast-pass possessors can feel like Dracula at a Transylvanian nightclub as they are ushered to the front of the line for VIP access to a trio of haunted houses including Phantazmagoria, a traditionally styled haunted house, Carnevil, a circus-themed attraction ruled by heinous harlequins, and Medical Malpractice, a new to 2011 attraction inviting guests to experience the horrors of the hospital billing bureaucracy. Occult aficionados can view the darker side of agricultural production as they attempt to extricate themselves from the 6-acre Scarecrow’s Revenge Corn Maze or take a trip on the Hanna Haunted Hayride into a foul forest filled with witches, werewolves, and chainsaw-wielding maniacs. Finally, mischievous imps can give friends a shot of adrenaline or humiliate faint-hearted frenemies with a trip through Black Out Haunted House, a devilish dwelling that ensconces explorers in complete darkness to realistically recreate the feeling of a literal death by chocolate.
