Mapleleaftickets.com have a special on pay for 4 days get 5th free at $210 or if you want to park hop then $251
Personally I would say the UK tickets for 14 day unlimited access at about £153 is better value then you can do water parks, Disney quest and all 4 parks as much as you want in 14 days. I feel the 5 day tickets are not good value even with a free day.
