A GM at an unnamed Marriott Property indicated to my friend, another Platinum member that "Platinum Members are a Pain". That they ask for too much, and are just too demanding. They always want upgrades, free meals, etc. This person did not know about the MI site, and really didn't care.
Personally, I do not think that most of us are too demanding. All I would like as a minimum is what Marriott has promised PP level customers. Most of us have a choice and have been supportive of Marriott.
Do you think any Marriott level customers, especially Platinum, are too demanding?
