Our next myVegas trade in was the Shark Reef at Mandalay Bay. Its an aquarium with tunnels so the sharks swim over you and in some spots the floor is open so they are above and below you! They have a ray / crab touch tank, jellyfish, a crock and a turtle which we couldn’t find among many other fish. Its regularly $18, again, not sure it’s worth it but a great activity if you are doing Vegas with kids. I just wish it was easier to photograph things through tanks!
