Stayed at Aria this past weekend and loved it. Actually, I never left the hotel because we were there to see Tiesto at Haze.
The decor, the architecture, the details and the technology were very impressive. I received great service during check-in. We were able to check in at 1:00 pm and get our room right away, luckily. We paid the extra $30 or so for a room with the view of the strip, which was worth it. The beds and pillows were incredibly comfortable. Everything was controlled by a touchscreen remote - curtains, lights, tv, music, privacy..amazing! We asked for a bottle opener and someone brought it up within minutes. We stopped in at our friends' master suite and it is so ridiculously wonderful..I suggest you save up some money and book the suite! I wanted to work out for an hour or so only to find out I had to pay a separate $30 fee..wtf! No thanks. That's probably my only gripe about Aria. Would definitely stay here again.
