I would stay here again. It's not perfect but I think we got good value for our money. To Brian F... I got cocktail service in the casino and I was with one other girl. I'm surprised that a guy wasn't getting served at the casino.
The first thing I noticed was the cheesy butterfly decorations hanging from the ceiling and that, ugh you can smoke in public places in Nevada : ( All of that aside, we got an upgraded room on the 30th floor that was quite large. It was clean and modern and the bed and pillows were AMAZING.
The casino was really nice, it's not as bustling as Caesar's or Bellagio, but that was fine. The patisserie near the elevators was a major guilty pleasure with the gelato (they do samples) and crepes. The restaurants are ok. The Aria Cafe was better than we expected as was American Fish, but BarMasa is an epic fail.
The location is great, I don't think the tram is really value add because it goes from Bellagio to Aria and at times, I thought it would have been faster to take the Strip.
