My toddler loves the aquarium and it's small enough that it's just enough for him. I think the biggest thing is the price, ridiculously overpriced for what you actually get to see. This is a very small aquarium, nice to have close by, just very small. If it were cheaper to get in we would visit more often. Since it is so small, it feels cramped. We've only been able to visit on the weekends and it's hard to maneuver a stroller through there with other people and small spaces. The shark tunnel is cool, but again admission is just way too high. We paid about the same to go to the Chicago aquarium and it took us a few hours to go through there, the Cleveland aquarium is maybe 30min to an hour max to see everything.
