I stayed at the Aria because I got an awesome deal or else I couldn't afford this place! I stayed here for 4 nights and it was extremely nice hotel! The view is awesome and I loved their alarm clock. The blinds will open and the TV will turn on. The bed was super comfortable and the staff were extremely nice. The casino floor is clean and free of smoke (maybe it isn't but I couldn't smell any smoke!) There was night, I totally forgot to put "service" on the door before I left and the housekeeper left me a message. And I called her back to ask them to service the room... how awesome is that? customer service at their best! haha
Although, there are couple things about the hotel which I didn't like/love. It's behind Crystals/VDara/Oriental Mandarin, so it's quite a walk to the strip/bus stop. The control were kind of hard to maneuver and the lights would randomly turn off. Also, I hate their sensor shit on the fridge, if you touch/move anything, it will automatically charge your room. But when you check out of the hotel, someone will do inventory and credit your account back. SO DON'T DO EXPRESS CHECK OUT, YOU WON'T GET A SALES RECEIPT OF YOUR STAY. The lobby is kind of a cluster-fuck, check in/check out is quite a wait.
But overall, I had a great stay here!
