Busch Gardens Tampa Bay announced new details for the eight haunted houses at its 18-night Howl-O-Scream gore and scare fest that begins with a preview Sept. 24. New is the theme park's Alone! house, which costs $24.95 extra if you buy a ticket in advance, $34.95 if you don't. Outfitted with several illusions, it offers one-on-one time being pursued in the dark by a deranged character actor. "It's a VIP experience guests told us they wanted that lets them navigate a haunted house alone rather than in a continuous stream of people," said Jill Revelle, Busch spokeswoman. "You can chicken out and go with some friends, but you don't get the T-shirt at the finish." Busch has updated the story lines in the other seven haunted houses, redesigned all scare zones while adding a fifth one, and upped the same-day, on-site general admission by $5 to $74.95. Prices on multiperson passes and widely available discounts remain the same as last year, clustered from $19.95 to $29.95. Also new is Sylvie, who writes songs about the fate of her ex-boyfriends for her "killer" rock band. For more information on this year's event, go to howl-o-scream.com/tampa.
