We visited Mandalay Bay on our honeymoon. My husband wanted to go to this attraction. I was reluctant because I am against exhibits with animals kept in tiny unnatural spaces. I agreed to go because he was doing stuff I was interested in as well.
Admission was about $18 a person. The whole thing is a walk through that takes no time to complete. I really did not think it was worth the money at all. He did take some pictures but I think there are better hotel attractions to spend money on.
