It's kind of expensive and we went in knowing that they are all about rescuing, rehabilitation, and release of animals but there wasn't much to see. If your kids love the Dolphin Tale movies then they'll love this place. If you're interested in learning about the animals and how they train, rehab, etc, then this place is for you. They offer some sort of talk every half hour but young kids can only sit through so much of those. The really fun experiences cost money (boat ride, feed the animals, etc). The gift shop is huge and they make sure that you walk through it on the way in and the way out.
Three of us spent about an hour and a half there and it cost $73 with parking. That doesn't even include what we spent at the gift shop. I would recommend going after 4:00 when the entrance fee is reduced.
