The biggest piece of advice I give is to arrive early. The park opens at 9am. You want to arrive the parking lot around 08:30am, head into the park, they sing the national anthem at 9am, and then you walk to the back.
There are two rides you can go on first, JTA and Kracken. After that, you can head to the first Blue Horizons show. If you are early, you can walk thru the Manatee exhibit first.
Eat lunch early at 11:30am, because the lines for the restaurants get long. My favorite place is Voyagers, located near the sky tower. This is cafeteria style, with lots of items to choose from and wood oven pizza.
Arrive to each show about 20 minutes early.
Don't ride the polar bear simulator, it will make you sick, do the walk thru instead.
Bring lots of cash to feed the dolphins in the Key West area.
You won't see everything in one day, but you'll have fun.
