MGM always has friendly staff, clean rooms, clean restrooms, a fantastic event center with many alcohol options and food options between the rooms and convention center. Only 2 complaints are no coffee makers in room and the smoke. I strongly dislike having to walk through the smoke to get to my convention. Rooms did not smell like smoke surprisingly, but my hair and clothing always did from walking through it all day.
