In addition to the Disney water parks, if you have access to a rental car, there are several independently owned water parks in the Orlando area that are worth checking out, especially for the young people in your group. There's Wet 'n Wild on International Drive, and for people who enjoy scuba diving and would love a chance to swim with dolphins, SeaWorld's Discovery Cove offers a once-in-a-lifetime experience. When consulting older tourist guides, be sure to keep in mind that Water Mania on Highway 192 has been closed indefinitely.
