Lots to see and do.
You arrive at 08:30am so you're at the gate early. At 9am you walk to the back of the park and ride JTA and Kraken. Then the Dolphin show, Clyde & Seamore, and eat an early lunch at the deli next to Clydesdales where you can get free beer samples. Continue to the Shamu show, play area behind Shamu stadium, walk thru polar bear exhibit. You'll be back at the front of the park. Start another lap, visiting the Key West area to feed dolphins around 3pm. Do the sky tower ride. Eat dinner at Voyagers wood oven pizza. Have a drink at the bar under the sky tower.
There's so many ways to see the park. The main thing is to do the fun rides first, so you won't have to wait in a line for them.
Bring lots of cash so the kid can feed the dolphins a few times.
