I love ARIA as a venue: the expo center is much more modern and fulled with natural light, when compared to several of the other similar locations in Vegas, which I have found to be quite dated and stuffy.
The rooms are really lovely here as well, with Large beautiful bathrooms that include soaking tub is in a separate section from the shower and toilet. There are also digital tablets in the room where you can control anything from lights, to room service, to music.
In general, the nightlife seemed a bit dull at Aria, but overall, The location is high-class and comfortable .
