What a fun day, just pick a nice weather day to make it perfect. The Sea Lion Show is excellent! I would focus on the show schedule the day before you go so to not miss any of the best attractions and performances. You'll laugh, and clap, and smile throughout. Be sure to arrive early, to see the pre-show mime at the stadium show. Do bring your own snacks to save your cash to just the entrance ticket price. The guy that does a lot of microphone broadcasting jokes, he's the best! Remember the SeaWorld daily show schedule is the key thing to know before you go.
