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.
