We visited to LasVegas for memorial day 2008 and we have a worst exp. with this hotel. We booked the non-smoking room through Lasvegas.com site, and when we reached there, the hotel staff told us that we r late(Bcoz of traffic through Hoover Dam) and the room we already booked was pre-occupied, and she was very unpolite. Atlast they assingned us a room, we r relieved and went to see the room. We noticed that it was a smoking room and the room was not at all clean and very disgusting. When we went back and reported her, she told us that the only room available was the room assigned to us and they r not at all responsible for anything at all.We r very diappointed . Later we went to JockeyClub hotel which is 3 miles away from Riviera. Eventhough it doesn't have a Casino, it is the best hotel with polite staff and very clean rooms. I never would like to recomend Riviera to anyone.
