This place was horrible.  I had to wait in a checkin line for 90 minutes, and then they gave me a room that was already occupied.  We used out key and went right in and the other person's stuff was all over.  I had to go back in and start all over again.  Then there was a long line to check out too, and they couldn't produce as bill because their computer was down.  Room had a broken door that wouldn't stay shut.\n[I am adding this update on 6/23/12 because of how Brittany H from Mandalay responded.  Despite this computer crash that left huge lines throughout the hotel on check in and check out, Mandalay Bay offered big discounts online and on twitter to still try to fill their hotel to capacity, rather than focus on the guests that they already couldn't keep up with.  All I hear is about how much they value their guests but this is baloney.  When I was there, top management only cared about profits.]
