As I return to consideration of buying DC points on the secondary market to add to my Marriott portfolio and go from Executive to Presidential, I just can't wrap my head around why Marriott would agree to the terms and why they would treat these points like those I already own. IOW, if I buy 1500 points for far, far less than what MVC is selling them for, why would all "privileges" I currently have accrue to the additional purchase. I understand MVC makes about $3 per point, but that's far less than the $24K they could get assuming a purchase of 1500 points. What don't I understand? Or is the axiom "something is better than nothing" the answer. Thanks all you smart people.
