On May 12 and 13, when hundreds of teams compete across the Walt Disney World Resort’s four theme parks in D23’s Great Disney Scavenger Hunt — the largest scavenger hunt ever to hit Walt Disney World — they’ll be vying for the ultimate Disney prize for the ultimate Disney hunters: a special preview cruise on the Disney Fantasy, the fourth regal vessel in the expanding Disney Cruise Line fleet. The special prize was announced today on D23’s Disney Geek, the weekly Disney news video podcast from Disney’s Official Fan Club.
