I am going to chime in with my 2 cents. First off try the code TNC10 it will knock of $25 per person. Your price is the price per person! The meals and snacks are included, all your drinks are included, including beer, and drinks! Their food is wonderful, and you can have as much as you want as long as they are serving still! So you could have lunch at 11:30 and again at 2 if you want! Snacks, you just walk up and grab them, it is very weird cause you almost feel like you are stealing, because you are so used to paying for things! LOL
Also, as mentioned before, that one person has to do the swim, I thought so as well, I had booked with my brother, because we had done the swim the year before, and he was doing it this past year, and we just wanted to use the park! I found out afterwards, if you call and book over the phone you don't need to have 1 person doing the swim, they said there online booking only allows for you to book with at least 1 person doing the swim!
Was it worth, YES, a 100x's over, we loved every minute of it, and it was worth every penny! I have never felt so relaxed on an Orlando, or any vacation as that day!
You would probably get more info on the Sea world/discovery cove board though!
