I have been to Vegas several times over the years and I have visited the Riviera before but this was my first time staying there.  First off they would not honor the room upgrade voucher that they sent me a couple days before.  Once we got to the room there was a huge stain on the carpet  right in front of our door.  Once we settled in we decided to hit the casino floor and we got stuck in the elevator for almost an hour and the fire department had to come and get us out.  It was so hot in there and I had to keep my girlfriend calm because she kept fearing the worst.  Once were were out the woman who worked for the hotel rushed us downstairs and had us wait at a table for about a half hour then came out and apologized for the inconvenience and offered us a couple of free buffets.  She was none too friendly and when I told her that being locked in a sweltering elevator merited more than a couple of free buffets she got even ruder.  The next day I asked to speak with the hotel manager and a woman came out to talk to us and said that she was sorry and gave me another number to call (Lacricia I believe)  I called the number and her receptionist said there was nothing she could do and tried to put if off on the elevator company saying that it was not the hotels fault because they did not own the elevators.  I asked to have the hotel manager call me and I never recieved a call from anyone else.  Our room never seemed to get cool and when I mentioned it to the woman at the front desk she brushed it off.  I didn't realize it until we were checking out but the floor in front of the air conditioning unit was all wet where I had my dirty clothes and some of the colors bled together.  Needless to say it was not a great experience.  I am still shocked at the lack of customer service and the fact that not once person called to follow up with any of my concerns.
