Seaworld is a spread out natural wonder. The various areas of dolphins, sharks, walrus, water birds, and orcas are quite a ways apart, so allow time for travel (there is no tram, the one thing I am most disappointed by). Staff even entertain the crowds while waiting for a scheduled show to begin.
The wonder is of the beautiful animals and how well trained they are. They seemed healthy and happy, and the kids were delighted.
I am not much on rides, but was talked into a roller coaster (a lot of fun, and obviously very concerned about safety) but I would not go on the one that flips you upside down. Not my thing.
Pleasant and enjoyable visit.
