This hotel is beautiful! Easily the nicest hotel I've stayed in on the strip. All the rooms are suites with a kitchenette, dining room, living room and large bathroom. Though, there are no rooms with 2 beds so if you have more than two people they will be sleeping on the fold out couch in the living room.
There is no casino and no smoking (thank goodness!) which I think is why this hotel was a little more quiet and relaxing than others. I never heard drunk people in the hallways or slamming doors at all hours.
If you are planning on relaxing by the pool you can reserve your lounge chair online ahead of time (for a small fee) and if you are with a large group you can all enter the same group name to insure all your chairs are together. Our group of 10 was able to lounge together right by the pool all afternoon. There is no way we would have found that many chairs together, much less poolside.
The location is great, right across from the Aria and a short walk to the cosmopolitan.
I loved my stay at the Vdara!
