For an idea of what might be inside that enormous space, read U.S. Patent No. 6796908, which describes an interactive Harry Potter dark ride in which tourists use RFID-enabled electronic "magic wands" to "cast spells" that affect the outcome of the attraction. The patent is from Creative Kingdoms' Denise Chapman Weston and builds on her company's popular MagiQuest fantasy games, found at Myrtle Beach and in Great Wolf Lodges. The concept predates Universal's plans, and both parties decline to confirm any partnership; but the cash to be made off selling collectible digital divining rods seems irresistible.
