A Real Parent's Story
She kissed a dolphin and didnt shower for a week
“My 7-year-old got picked for the dolphin kiss during the show. Best $15 we ever spent.”

The dolphin experience program was next level. She got a dolphin kiss on the cheek and the photos are our screensaver still. The aquarium is world-class with huge tanks, jellyfish gallery, and arctic exhibit.
