Crowds: moderate. The line for the aviary was ridiculous as they only had one side open, take 8 people at a time for 3 min visits. We waited about 30 mins in an area that was not conducive to a line since people needed to walk by.
Exhibits: Most were pretty interesting. The interactive part was neat. Some areas seemed dangerous as they have rocky steps that could become wet and deep water. I guess it's all about how smart the guests are. Some exhibits were empty (fish). It all felt somewhat gimmicky and crowded.
Price: Overpriced for the experience. $15 for adults and $10 for kids. For a bigger place it would've been worth it. You can also purchase activity coins to feed the fish/birds.
Overall: It was alright for a one time visit. We likely would not go back because it just felt like a lot of water, a few things to pet. The highlight was the bird stage.
