While weight loss can be achieved without sweating, it is possible to lose weight from sweat. Since sweat is made up of water (which is heavy) and sodium from electrolytes, you will automatically lose weight immediately. Unfortunately, this type of weight loss is only temporary.
MGM Grand Distance in Straight Line. The distance from Mandalay Bay to MGM Grand is 0.76 miles (1.23 kilometers) in straight line. Walking at a normal rate of 3 miles per hour in a straight line, it would take 15 minutes between Mandalay Bay and MGM Grand. See below for the estimated time (more realistic) if you walked along a street route.
Have stayed at Mandalay Bay a couple times. Location is not an issue. As stated here allready the free tram gets you to the Tropicana intersection (NY/NY MGM Showcase mall ect) and the deuce (bus) gets you everywhere else.
