Vdara is a really great hotel, nice rooms and amenities etc. Best part is non-smoking throughout the hotel and there is no casino which means you are not gasping for fresh air every time you go through the lobby - is standard in almost all Vegas hotels. Also note the pool was not open, so meant we had to go across the complex to the sister hotel the Aria to use the pool. Not a huge deal, but would have been nice to not have to go so far.
Other than that, do not expect any housekeeping services such as made beds or change of towels. Not a big deal unless you are staying more than a couple of nights. We had three people in our group and all rooms have one king bed and a pull out couch.
We had to get housekeeping to bring bedding for the pullout late at night as we did not expect it would not be made up. The pullout was very uncomfortable, so better to not have more than two for the room or perhaps for kids.
The kitchen is a disappointment since there are no dishes, not even a bottle opener or a coffee maker. Options for food in the lobby, and lots more across at the Aria hotel.
All in all, nice clean room and close to the strip.
