Heading to Sea World are you? That’s cool. It’s a pretty fun place the first time. (We got annual passes one year and discovered the fun wears out pretty fast on the third visit and beyond in a year.) Anyway, here is the best source I have found for getting tickets online. Tickets ain’t cheap though — at $61 per adult ($52 per child) you need to be prepared. I guess it isn’t that much compared to Disneyland, but I know Disneyland and you Sea World are no Disneyland. (Sea World seems more comparable to the San Diego Zoo to me and they are only charging $32 per adult fer cryin’ out loud!)
Anyway, don’t let me discourage you from going to Sea World or anything. It really is a good time and the shows make for great family fun.
BTW – Bring some extra dough for parking. If I remember correctly that ain’t cheap either.
