I wanted to respond and tell you I agree with planning your day based on the show schedule. Sea World is huge! For some reason it seems bigger than Disney parks to me. It might be that it has the huge lake in the middle and you have to walk around that, but even doing that at Epcot, Sea World seems bigger. Anyways, if you want to see a show and you are on the opposite side of the park, it makes it hard to get across the park quickly, even with the walkway across the lake that you can take. My best advise would be start on one side and just make a circle, and hang out in those areas until you see that show. We always start on the "left" where you feed the dolphins, and move in a circle that way.
