I feel as though one visit to Shark Reef is enough. Regular admission is $18 and $15 for locals. Pretty steep pricing for an aquarium that only takes about a half hour to walk through. Nevertheless, it is a nice place. My favorite part was probably getting to pet the baby stingrays and horseshoe crabs in the touch pool. The gift shop at the end is awesome. Not really impressed by the exhibits, but if you're on vacation it's a cool spot to explore.
