Aquatica and Adventure Island, over in Tampa, try to make it a "family experience". Not too many big thrills. Haven't been to Wet & Wild so I can't compare. One thing that would make me forego the "bigger thrills" is the fact that Aquatica is only a year old and fairly neat and clean. At Aquatica you can rent a private cabana for the day (don't know if Wet & Wild has them). Granted it's not cheap but we've done it at Aquatica as well as over at Adventure Island and found it to be worth the money. They close up on all 4 sides when you want privacy (great for avoiding a crowded changing area if a storm pops up) or a nap, there's a fan inside, a fridge stocked with water bottles and or sodas, you can order lunch and have it brought to you cabana, there's small locker, you're away from the crowded "beach" areas and always have your own chairs when you want to relax. Have fun wherever you go!
