I have 131 nights with Hilton and Marriott just gave me gold. I have a whopping 4 night with Marriott (technically 1 because 3 was the woman staying under my name w/out me). I called in, talked to a rep, faxed in a screenshot of my HH account and just got a call back they are comping me gold. No challenge, just comped me right to gold. When I called at first the rep put me on hold, talked to a manager, and came back to tell me their manager said they would give me gold after 50 night. I (somewhat sarcastically) thanked him and explained that is what it normally is. He went to talk to another manager who said to fax in the docs so it seems to be pretty much YMMV based on who they ask. I sent a note along with a screenshot explaining the amount of business that I'm doing with Hilton, anticipated number of upcoming stays, etc and expressing my desire to stay staying with Marriott more often. Just booked two weeks at the end of next month and I'll book another month if that goes well.
