This was a pretty nice aquarium and I guess for being on the strip $18 isn't that bad. My only complaint is that it was pretty small and we were able to walk through the whole thing in about 20 minutes. I like that you could touch a stingray and I enjoyed the shark tunnel but these are all things i can see in a much larger venue at the Monterey Bay Aquarium. If I were to do it again I would see if I could get cheaper tickets at one of the discount places like tickets 4 less or see if they give reduced rates to locals and bring my uncle (who lives in Vegas) with us.
