Does the MGM Grand in Vegas still have the greatest amount of rooms in the world?
MGM was the largest for so long. In Vegas the Venetian has more but not considered the same way as the MGM. The Venetian has the Palazzo which is a separate hotel and booked separately so I would still consider the MGM the largest in Vegas because if you include the Signature at MGM it would then combine to surpass the Venetian/Palazzo. The two properties Mandalay Bay shouldn’t even be on the same page as they are so different. Glad you found out before you went and you are right … there is no indoor pool at Mandalay Bay.
