I stayed two nights at GN last October in a Gold Tower Luxury room.
The hotel was nicer than I expected. The ventillation has been improved so the heavy smoke wasn't a problem. The room was definitely nice, however, I was there as a cash customer, used a deal from the LVA hot deals, and the hotel took off an additional 10% at check in when I showed my AARP card.
They also would have taken AAA auto. Next time I would not take the luxury room, basic dleuxe would be fine. Rush Tower looks nice, but a little darker. I didn't want to spend the exra money for Rush.
I was there Thursday and Friday night, I did see that many $25 tables were up to $100 on Friday.
I did use the LVA discount book and had a fun time at some comedy shows, dinner at Binions Steak house, and Vic and Anthony's at GN was really good.
The pool area was very crowded with mostly well feed 30 to 40 somethings drinking beer out of a bottle. More cowboy hats and confederate flag tatoos then you will see on the strip.
After two days I had enough. Basically I prefer the gaming elsewhere.
RIO is a good option if you are on a budget. I don't mind the shuttle to the strip, the restaurants aren't great, but good value. Comps are easy to get. I have always found the crowd friendly.
