Then you got pissy because your upgraded room wasn't ready when you were arriving mere hours before your important presentation? And then you called Marriott corporate to elevate things to that level, and are upset that the GM was rightly miffed at your entitlement attitude?

Then I have to question your judgment further if you KNEW that the GM and your Group Rep are "close" but you somehow expected them not to communicate?

It sounds like you were behaving like a spoiled brat, other people noted it and talked about it (behind your back, you no doubt feel), and you're inventing a new slight to get upset about. I suggest that you rethink your attitude, behavior, and inflated sense of worth.

To answer the question on the bottom of your post, "Is this a gross invation of my privacy as a Marriott guest, or am I missing something?", you are most definitely missing something.
