This Sea World is different than the other two; they have roller coasters and a huge water park. When you buy one ticket you also get a second day free-so, the price isn't bad for all you get. The shows are well prepared and fun to watch, there's something for everyone. My husband loves the roller coasters, I love the shows (which vary throughout the season), and my kids love the water park.
I'd recommend purchasing a season pass-it's the price of two regular tickets and you can go anytime between April and November; definetely worth the price. We use our season passes as our 'swimming pool.' We go for just an hour or so and go for a swim at least once a week.
