The Seaworld camps are fantastic. I would highly recommend. You are issued a toll booth pass and you drive right in and take a sharp right into the parking lot they use for corporate event parking. You walk with your kids into the corporate picnic area where they have the various age groups divided up (this age group under this shelter and that age group under another). It is HIGHLY organized chaos with all the kids. Activities vary based on ages but all get to go behind the scenes to some degree. In addition, they all go into the park and see the shows and rides (without waiting in lines). They also get a chance to interact with some of the animals (feed the dolphins for example). My wife and I bought the kind of ticket where you can go as many times as you want for seven days. So a couple of afternoons we picked up our boys after camp and they excitedly took us around and showed us places they had visited (they can into the park after camp).
I have to say, it's just like any other camp-- sometimes you have great camp counselors and sometimes you get a dud. Admittedly there are more girl counselors than boys. Thankfully, our oldest had a guy who understood how to interact with boys and avoided some of the "girly" camp cheers and crafts and treated the boys like boys (splashing contests and competition type events).
Typically you drop them off at nine and pick them up at 3:00 or 3:30. My wife and I drove over to Winter Park and had an excellent lunch at a trendy restaurant and took a boat tour of the canals and lakes and saw some HUGE private homes. Had a couples massage one day at the World Center Marriott. On another day we went into Seaworld a few hours before picking up our kids and happened to spot our boys with their groups without them realizing it and got some great candid shots of them. We also had an adult lunch at the shark grill (expensive) and took our time to soak in the atmosphere since we were not in a hurry. .
Our boys have begged to do it again.
If you are going to do, you may want to become a member for the discounted rate. Our membership lasted two years and we made a return visit a year and a half later for the Christmas lights.
