I visited during shark weekend, so there were shark-themed activities like sidewalk chalk, pictures, a show and tell guy (shark teeth, sting ray bar, etc).
Parking was $5.
The shark tank is cool and there's a tunnel where you walk through it. Now there are lounge chairs in the petting area.
It's a small place. I walked through the entire thing in an hour and I probably read like 10 info plates.
It will be great in a few years, with the expansions.
