UK visitors to Walt Disney World can currently purchase a 14-Day Ultimate Ticket for the same price as a 7-Day Premium Ticket (for use in 2011).
The saving is not huge, with 14-day Ultimate Tickets actually only priced marginally higher (in the region of £10-15) than 7-day Premium Tickets on most websites. Tickets must be purchased by December 31, 2010 to qualify for the offer.
The Ultimate Ticket allows unlimited admission to all four of Walt Disney World's major theme parks. You can also take advantage of Park Hopping, giving you the freedom to visit more than one theme park on the same day. The ticket includes unlimited admission to both water parks, DisneyQuest and Disney's Wide World of Sports.
