ZZZs in the Seas


Ever wondered what the Aquarium’s animal residents are up to after we close our doors? Find out at ZZZs in the Seas, our afterhours slumber party. Spend the night exploring the Aquarium and discovering interesting facts about freshwater and saltwater species. A guided tour, animal encounters, SCUBA diver talk, scavenger hunt, evening pizza and light breakfast are included in the overnight experience. Who knows? You could end up counting sharks instead of sheep!

Next-day admission is also included with the overnight package. Guests must exit at 9am when the program ends and can re-enter at 10am when the Aquarium opens to the public.
