Recent stay at Aria was very good. Rooms are still probably the most technologically advanced on the strip - The controls are cool to use (you can turn on/off lights, open/close blinds, set moods, etc.), but they do have a little bit of a learning curve. The place feels luxurious without being pretentious. There's a Starbucks and a Fresh Pressed Juicery on the Promenade level, which was very convenient for a quick morning drink. Lots of great food options including an underrated buffet and quick access to Monte Carlo's food court if you are looking for budget friendly options. Also really enjoyed the high quality live music at the Level bar on the casino level next to the room elevators.
Note* - Check-in line was super long. You can take advantage of their mobile check in feature - just check-in ahead of time and you'll get a room preassigned. They have a separate mobile check-in line which was a lot shorter. Only downside is that your room is preassigned so it may be a hassle for them to change your room if you prefer a higher floor or closer proximity to the elevators or something.
