We just went, so here's my best shot at a detailed description.
You arrive and go through security. Then you go to a check in desk where a picture is taken of you. The picture goes on a plastic ID card which you wear on a lanyard around your neck all day along with a plastic card with a map of the park on it. This lanyard must be tucked into your wetsuit or vest when swimming with the dolphins. At check in you are also told your dolphin swim time.
You take a brief tour and your complimentary welcome photo is shot. Then you are directed to an area where you select either a wetsuit or vest. You get a snorkel bag with a snorkel, mask, and complimentary sample of dolphin safe sunscreen. You get to keep the snorkel but the mask and bag get returned. Before your dolphin swim you go to a cabana for a brief video and instructions. You cannot take anything in the water with you although I recommend aqua socks because it is a simulated lake complete with rocks you can stub your toes on

We got to give the dolphin ice and fish and get to know and give her a kiss before swimming out about 30 feet and being towed back. You do this in groups of 8 and there are four groups in the lake at a time. The dolphins do jumps individually and in groups.
In addition to that, there is an aviary with all kinds of birds that are so tame they will come land on you. You can get cups of food to feed them. I think there's a fawn or two also but we didn't see them.
There is a coral reef full of tropical fish in it as well as some huge sting rays. (Their barbs are trimmed of course.) There are also windows you can swim up to and see barracudas and sharks.
There is a ray pool so that you can touch rays.
Additionally there is a large fresh water pool heated to 80 degrees with waterfalls, a cave, and a 'lazy river' that also goes through the aviary.
In addition you can eat and drink all you want. I believe lunch was from 10-3 or something like that. There are a variety of menu options. You can also have snacks all day. They offered a variety of individually packaged crackers, cookies and chips. You can also have all the Anheiser Busch products, pepsi, water, coffee, tea, water, hot chocolate, or pepsi products you want.
You can link your ID to a credit card so you can leave your wallet in your locker if you want, and your ID also indicates whether or not you are 21 for the adult beverages.
The showers contain crabtree and evelyn shampoo, conditioner, and body wash,towels, and even plastic bags for your wet clothes.
There are white sandy beaches w/ beach chairs and even a hammock. Basically, it's a tropical paradise....
Is there anything you still have questions about?
