Review for Grand Biloxi Casino Hotel & Spa Review For Grand Biloxi Casino Hotel & Spa Google User Feb 26 '17 at 1:28 Great location. We weren't staying as guests but hitting the casino and grabbing a bite to eat. Service was good overall but one of the slot machines had a malfunction and we had to wait 45 minutes for an attendant to cube refund our money. Overall, if recommend Harrah's.
