For vacations of 11 days or more, or if think you will return to Walt Disney World within a year, think of getting an Annual Pass.
If you’ll be buying Magic Your Way Tickets with the Park Hopper option and also plan to visit a water park and/or DisneyQuest at least one time, it’s cheaper to add the Water Park Fun & More option than buying a separate water park or DisneyQuest admission. The cost of upgrade would be $23.43.
If you’ll be buying Magic Your Way Base Tickets (no Park Hopper) and you plan to visit the water parks and/or DisneyQuest two or more times, getting the Water Park Fun & More option for $60.71 is cheaper than two water park or DisneyQuest admissions.
If you’ll be spending a bunch of time at the water parks or DisneyQuest, think of getting a specialized annual pass for that one option (For example, Water Park Annual Pass). It might be cheaper than buying individual admissions, adding the Water Park Fun & More option or upgrading to a Premium Annual Pass.
