I've been to all of the City Center hotels and ARIA has been by far the WORST experience I've ever had.\n\nUpon arrival, I was greeted unpleasantly by the worker.  She had my girlfriend and I wait due to their computers being down.  We waited with other guests for 20 minutes then came back to the counter where she didn't even apologize for the wait.\n\nI ignored it and just wanted to get to my room.  We get our keys and go to the room and our room was already booked.  Someone was inside our room (30159).  It turns out the girl wrote the room number wrong on our card, it was suppose to be 30156.  REALLY? Are you really that dumb? I felt it was deliberate and came down and complained about her rudeness and our situation.\n\nThe new person was nicer and apologized and said she'd credit me 28 dollars back to my card for the resort fees.  Total lie. When I left after our 2 nights stay, they still charged me for the full resort fees for both days.  \n\nThis is the worst experience I've ever had at City Center.  Vdara, Mandarin Oriental and Cosmo were FAR superior in customer service and handling situations.  I cannot recommend this hotel and I will not be staying/visiting again.
