Review for Diamond Mountain Casino and Hotel Review For Diamond Mountain Casino and Hotel Google User May 17 '18 at 3:40 The hotel has fairly nice rooms , especially for the area and the customer service is good. They even brought a mini fridge to my room at my request. The slot machines didn't pay all that well for how much was spent and you have to call an attendant to cash out unless you sign up for a players card. Although the card did make it easy to transfer money from one machine to the next. They did have a good selection of machines to choose from for a small casino. View full site to comment or like
