Rooms were ok, they always say they upgrade there rooms but they are so dirty. I get it, its Vegas but do some quality control here if your going to tell your guest something down at the guest check in make sure you know what's going on in your rooms. I love Vegas who doesn't. But I feel disappointed every year as the prices increase and the room get crappier. Just welcome me and let me be on my way dont tell me I have an upgraded room and I expect to see that and I get something different, especially at 200 bucks a night.
