I wouldn't stay here again. The walls are thin so you can hear the cleaning crew vacuum at 7:45am. They also don't have the basics, like coffee in your room, so everything is a bit of a hassle.
The rooms are advertised as "corner view" rooms, but they are just regular ole rooms. The concierge told me its just an advertising tactic Aria uses because of the way the building is shaped, but it definitely misled me when I booked.
The spa is meh, but definitely not as nice as Wynn or even Mandalay.
I also have about $80 in random "salon" charges that were added after checkout, but I am sure they will take care of those.
