1 star. My girlfriend and I bought the groupon for this trip a couple months ago and finally used it last week. We booked our hotel room and got our reservation at the Riviera. What a mistake. Not only were we greeted by an unfriendly and unhelpful staff, the lady actually is yelling to her co worker behind the counter about how we are slowing everything up and now she can't go on her break. We got there and they didn't have our reservation!! What the hell!
