SeaWorld is great for everything many have mentioned above me.
The man who came up with the concept of SeaWorld was a huge fan of Walt, and I think so is August Busch III, the current Chair of Board. He bought the parks and comes in all the time to make sure they're up to his standards. He knows his parks are not on the same wave as Disney or Universal, but like someone said, petting a dolphin was the thrill of the day, not dropping from ToT (which is a great attraction).
The new water park is supposed to be really good. I don't think the Busch Corp. will cut the check for something that's not going to compete, especially with it's stock down and beer business flat. I'm honestly expecting Blizzard Beach to be squashed by the new park... But time will tell!
And remember, SeaWorld is the only place in Orlando who will hook guests up with free beer and free food! Don't believe me, head to beer tasting at the Beer House! Great fun there!
