I stayed in Casino Royale for a few days in April 2013. I was in Las Vegas on business and not interested in gambling, drinking smoking, etc....
The greatest thing about Casino Royale is that the hotel section is quite small, just 4 floors, and you get in and out in seconds. From the hotel elevator, you're just a couple meters (a few feet) to the street. You do not have to walk for ever between noisy gambling machines, smokers and drinkers like in the larger casinos.
As the place is small, I was instantly helped at the reception when checking in and out. No endless queues here!
The room is all right, with everything you'd expect, including a coffee machine. Internet was free, fast and efficient in my room (#407).
