Review for Mandalay Bay Resort & Casino Review For Mandalay Bay Resort & Casino Google User Jan 21 '19 at 4:33 My husband and I went to The Shark Reef, which is basically a small aquarium. It also has a portion about the polar regions, and is very interactive. The aquarium was not huge, but is very beautiful and well done! It is worth the $25 adult priced ticket. It is a great activity for adults and/or kids. You can pet sting rays and horse shoe crabs. View full site to comment or like
