Very cool, high tech rooms! Stayed here last June on a business trip that was for a conference being held in the Aria. I was very impressed with the tech in the rooms. When you first walk in, the lights come up slowly, the curtains open and the TV comes to life. It has a very Starship Enterprise feel about it. As you would expect in a new, top-end, Vegas hotel, the bed was very comfortable and the towels were plush and nice. I didn't have any need to talk with the staff, so I can't comment on some of the bad experiences others had. My check-in was quick and courteous, though.
Overall, I would go back if it were a business trip but on my own dime I'd probably stay elsewhere.
