I find Sea World to be a different experience than any WDW park. It's wonderful. We never really have a "touring plan". We arrive, check out the show times, decide which ones we want to see and plan around that. The Shamu show is the obvious "must see" and only offered a few times during the day. The stadium is very large (as large as if not larger than the one for Lights Motors Action). Our next fav is Blue Horizons. While it doesn't have the killer whales, it has so many other other animals (including birds) and trainers that in some ways we like it better than the Shamu shows. They also have a cirque du soeliel type show and a couple of smaller shows with "pets" and sea lions/otters. If you have an entire day going into the evening, I'd say you can pretty much do it all but you'll be tired. I always try to pick shows and attractions that I might not get see locally and do those. I can see a sea lion/seal show at home and while it's probably better at Sea World, I can't see a show like Shamu or Blue Horizons or go through a shark exhibit like they have or the artic exhibit. I like to have a day where I don't have to be a "park commando" or have a schedule. Enjoy Sea World!! Visit their website too to help in your planning.
