Universal Studios Orlando will feature eight haunted mazes, six scare zones and two live shows at Halloween Horror Nights 21.
Universal Orlando's Horror Nights has been voted the best Halloween theme park event for the past four consecutive years by Amusement Today, an industry trade publication.
Lady Luck, the icon for the Florida theme park's 2011 event, will transform each night from a tempting seductress to a bloodthirsty beast.
