December 2014, I stayed at the Mandalay Bay Hotel for a professional conference. Let's just say I was disappointed. I expected a lot more than I received. I was placed on the 5th floor, right above AC units. Let's just say the first night I got NO sleep. I had to attend conferences the next day but I was exhausted. I asked to change to another room and was given the 14th floor. It was slightly better but I could hear the traffic from the strip. I did have a great view. The second room was not clean completely and it looked like the housekeeping staff half ass cleaned it. Their room service menu was limited to say the least. Burger and fries and cold sandwiches were all that were available. I mean c'mon you charged $150 per night you should have a gourmet room service menu. I was very disappointed and not sure I will go back again.
