Ft Wilderness to Sea World's water park was only like a 20 minute drive or so. My sone who is one of those tech savvy gurus used his phone/maps for directions. He was on cloud nine. FWIW, we stayed at Ft Wilderness from Sat night to Thur nite. Sunday: Kennedy Space Center. Mondy: Sarasota area. Tues. Disney's Animal Kingdom Park. Wed: Stayed at the CG. Thurs: Universal's Water Park.
Be advise, Orlando is in midst of major road work, one end to the other. Probly going to be a couple more years before done. Sorta same thing in NC area (Charlotte--if I recall right).
