It's like having a miniature sea world in vegas minus the dolphins and whales. It's a great family place! So I purchased the pogo passes for me and my kids and this was one of the venues included. My sons favorite spot out of all of it was the sting ray tank.
In order to feed the animals and sting rays you need to purchase tokens which to be honest I felt they are a little overpriced. I would recommend pre-purchasing online.
We went on a Wednesday afternoon for my nephews birthday, it wasn't overcrowded. My kids and nephews were able to enjoy everything. The staff was friendly and helpful to some extent. It was a great place to spend a few hours at. Many different thing to see!
