Well, we just received at least a partial answer to my Platinum upgrade question. On arriving Saturday at Las Mimosas Beach Club in La Cala de Mijas, Spain, we found we had been upgraded from a 1BR unit to a 2BR unit. When I notified them 2 days in advance of our estimated arrival time, I (politely) mentioned we were RCI Platinum and requested an upgrade if one were available. On check-in, the manager directed us to a 2BR unit. From what I can see, the resort, though small, is not fully occupied (it's off-season still)...and we seem to be the only RCI guests. Las Mimosas is very neat, clean, and comfortable resort with a friendly and very helpful staff...and very nice restaurants and tapas nearby, several in walking distance. We would certainly stay here again.
