About 2 hours. It's worth the time.
I would say about an hour and a half two hours tops. Some stuff was so awesome we went back through a second time to see everything again.
Would agree. ^^^ If you're really interested in the whole aquarium you'll spend a good hour to hour and a half there. There's a station about half through to get food and drinks while watching the stingrays swim around. There are a few hands-on things closed due to Covid, but still a lot to do and see. There's even a play place for kids.
One hour minimum.
I would say an hour, on average. It mostly depends on if you stop to read about every display, watch every educational film, etc. You could easily spend a lot more time there if you wanted.
