We checked in and there was a bad Odor in our room. Food was left in warm refrigerator. Called and they said that someone would come remove garbage but we wanted to switch rooms. They told us our new room and said they would be there in 5 minutes. It s been 30 and no one has helped us even though we were told several
Times they would be right up. Hotel is huge and it s not a quick walk back to reception.
