How many days do you plan to spend in the theme parks and/or waterparks? Be aware that the more ticket-days you purchase, the less you pay per day. A one-day ticket is $100+; a 10-day ticket is roughly $41/day. You can also add on the park-hopper option, if you wish to do more than one park per day. There is a Water Park Fun and More option to add to your ticket, although you may save money by purchasing your water park tickets separately.
