worth $18, no not at all. I only went because my family was in town and they have kids and we needed kid friendly things to do. It was nice but nothing spectacular! I think we walked through the entire place in about 25 minutes. Some interesting fish and some cool sharks. The best part was the tunnel you walk through and you are covered in fish and sharks from head to toe. The man who ran the sting ray area was a little annoying, treated the adults like children and it was pretty annoying. The lady that was the security guard where the piranha's were was not friendly. She did not seem like she wanted to be there and when we asked questions she mumbled so much I couldn't hear anything. Will I go back.....no! Did I have a nice time, yes. But not worth what I paid. If you are a NV resident you do get a $3 discount.
