Went to the course as they participate with Troon Card. However, the course needs to take some lessons in customer service from Troon North or The Phoenician, where both courses make you feel welcome and that they are happy you are there. After 15 mins of checking, they finally honored the Troon Card rate. The rest of the day was great as the course is fantastic. So 2 stars for customer service and 4 stars for the course = 3 stars.
