Here is a vid I shot at Aquatica where we went for my 8yr old daughters birthday.
Now a little bit of comparison. For sheer experience, you can't beat Typhoon Lagoon. I've been twice and loved it both times. It's thrilling enough for the big kids, and has enough tame stuff for the little kids. Blizzard Beach is a little on the scary side for little kids, but still good. Aquatica....there is not a lot of shade at all. The beach is ungodly hot, but hey it's an authentic florida beach! The rides here are not too scary for the little ones, but some may be too much for little ones. Dolphin plunge is one that I thought my daughter was going to hate..dark confined spaces, all alone, big splash at the end....yeah we rode three times. Forget about the wave pool being anywhere near as good as TL. It's not...doesnt mean the park is bad...just different. The animal experiences are okay...but minimal. I am NOT a disney person at all....so this is as about as realistic review as you're going to get.
The play area, I had so much fun in, as well as my kids. We are a bit sadistic so we spent at least an hour dumping water on peoples heads as they came by. One person said "HEY STOP! YOUR GONNA GET ME WET!" At which point my daughter laughed and dumped another bucket on his head. The lines during the day get rather long, but as many people said, do it in the morning or late afternoon. Calms right down. Lots of family slides to do, at least four, and there is a section of slides for little ones as well. Two lazy rivers...one you actually use to get onto one of the slides, the other is a speed river, in which you use provided life vests and go speeding around the pool. Its great. Overall a good place to try. Not disney, so dont go crying that it's not, you've been warned, but definately good.
