Given that watching fish can lower your blood pressure, it’s practically a public service for Mandalay Bay to provide this facility in a city where craps tables and other gaming areas can bring excitement levels to dangerous heights. Although I admire the style (it’s built to look like a sunken temple), and standing in the all-glass tunnel surrounded by sharks is cool, it’s just a giant aquarium, which is disappointing at these prices. Certified divers can get up close and personal with more than 30 sharks in the tank with a guide, if you dare. Note: It is waaay off in a remote part of Mandalay Bay, which might be a hassle for those with limited mobility.
