Had a pretty good time with my two year old. I went as soon as it opened at 10am sharp to beat the crowds. It got busy very fast. I purchased about 12 tokens and ended up only using 2. They do not give you refunds on tokens but you can use them to purchase their junk toys in the gift shop, which I did. I was disappointed how high a lot of the exhibits were. My 2 year old could not really do much. He pet a start fish after I had to hoist him up. He was really scared of the birds as they were really hungry. One of the birds pooped on me.. LOL I really thought feeding the birds was pretty cool. I guess there is not much like it in Vegas. I felt somewhat bad for the animals since the place is PACKED. Those animals are getting petted, fed and their water tainted with all day.
The place has a lot to improve on. Considering how many people are there, why not get their concessions going better. They had no food out when I went and the food they were selling such as chips, cotton candy, etc was gross. They could be making a lot of money here and they just don't see it I guess. Also, they needed to have more employees around. I went to the shark area many times and no one was ever there. It would be nice if they gave education tours or something with a microphone so that people can actually learn a bit about the animals being displayed.
