Review for Desert Diamond Casino & Hotel - Nogales Highway Review For Desert Diamond Casino & Hotel - Nogales Highway Google User Dec 12 '16 at 7:01 It was fun playing the slots and the service was good. Often someone was coming by to offer complimentary drinks. I just wish they had a no smoking section of the casino.
