Just got home from Mandalay Bay and they are hard at work changing the casino carpets right now. They are constantly working very quickly 24 hours a day. I heard it will be finished by this weekend. They block off sections of the casino and move the games/tables while working on the area. It was pretty interesting watch them work. The new carpet is like walking on a cloud and it makes the casino look nice and fresh! We would walk across the old carpet onto the new carpet and it was such a huge difference!
