Review for Desert Diamond Casino & Hotel - Nogales Highway Review For Desert Diamond Casino & Hotel - Nogales Highway Google User Feb 2 '17 at 21:48 All in all I would give Desert Diamond Hotel & Casino a 4 out of 5 star rating, as far as Tucson Casinos go. This is my favorite casino to go to here in town, based on slot selection, room quality, & location. The room I stayed in was a suite, & in that aspect I have no complaints. My only complaint is that every time I go, no matter what time it is, some section of slots is always roped off & not accessible. This definitely gets old, especially when it's your favorite machine That is off-limits. As far as Nationwide, I'd rate this casino at 2. Only because its not in the same league as the casinos in Vegas. View full site to comment or like
