We went there a couple of times including "Trainer for a Day" program. That took a big hit on the wallet. Last time was a few years ago. We got there at opening and stayed most of the day. Don't bring sunscreen because they provide an environmentally friendly one. You are greeted, sign in and are given a personal tour of the front of the park. They provide a wet suit and a locker to store your stuff. You get an expanded continental breakfast and are given the run of the park.
When it is time for the dolphin swim (which we did early), you meet in the designated area and are assigned a trainer and taken to a cabana with a group of about 10 people. They give you do's and don'ts. For instance, no jewelry unless it is a wedding band that won't come off. The experience is cool with a fair amount of interaction with the dolphin. Be prepared to buy the photo package they sell.
Lots of stuff to do and DD loved it. The stingrays were a big hit. You also get lunch and when it was owned by Bush, FREE BEER. Not sure if the beer is free anymore. I let the kid run around to play with the stingrays and had a few.
Attendance is limited and it isn't crowded at all. Food was a little better than OK. The animal interaction is very good. Expensive but it was worth it for us. She loved the animals and had a blast.
Let me know if you have any other questions.
They also had a dolphin named CJ and when we did the Trainer for a Day, they brought him out to meet us. If he is still there, tell him I said hello. Here he is.
Two thumbs up with a Z snap.
