I got comp'd platinum from Marriott. I sent them my Priceline history at the Fairfield Inn in question, my paid stays since I joined MR, my plans for 2004, and a copy of my HH diamond card. I requested a status comp, level unspecified.
They came back in a couple of weeks with a Platinum comp.
I'm happy, and I'll make Plat this year easy.
Check other threads for the phone number in Salt Lake. Talk to the folks there; they can be very accomodating.
