I've been to this hotel on multiple occassions for business and pleasure and its my preference at the moment in Vegas. The majority of the rooms are all the same and labeled as 'suites'. You have the main entrance to your room, the bathroom and bed immediately inside and then you get this 3 step strairs to the "social area" or whatever you want to call it where you can gaze out over the Nevada area. I've never had an issue with service, from checking my car in with valet to my room and leaving again.
The upside - This casino has a lot going for it. Location is fairly nice being central on the strip. Its surrounded by other nice hotels too. I'm not a smoker but this is Vegas but this hotel has managed to strike a nice balance. In major walkway routes through the hotel and other heavy traffic areas like food areas smoking is not allowed and security or staff will ask you to move along. Smoking IS allowed on the casino floor and in most other areas. Overall the ambience is great and its very enjoyable.
The downside - You're going to pay a little more for your hotel room.
One of these days I'd love to get a super awesome room at the upper most floors and if I manage that while the hotel is still awesome, I'll update my review which will probably push this to 5 stars.
