through the gates, if you go off to the left, there is a dolphin pool with underwater viewing and above water viewing. Also, there is an aquarium with big stuff in it (sharks, etc.)

You have to get into their parking lot to get to it. Every time I'm there I'm amazed at how good the stuff outside the gate is and I think if I only had an hour or didn't want to spring for tickets, I would be super happy just to see those two things. The aquarium itself (Explorer's Reef) is well above average compared to aquaria I've seen.
