Howl-O-Scream returns to Busch Gardens Tampa on Friday night (Sept. 21) for 19 nights this season (Sept 21 through Oct 28). This year’s event features two new haunts: Insomnia - Every door in this haunted asylum leads to your worst nightmare and the doctor is accepting new patients. Fears turn into fate as victims are forced to stay awake and receive twisted treatments from demented doctors. Simon’s Slaughterhouse - By merely stepping inside, you have agreed to play Simon’s sick and twisted games. Entering this horrifying realm requires a journey through the Meat Market where cannibalistic creatures feast on the weak as they add to their Monster Menu of human hors d'oeuvres.
