I didn't get a match, but I did get a comp to platinum (!). At the time, I was Diamond with Hilton, and I had a history of doing business w/Marriott, as well as future plans. I spoke with the folks at SLC, and wound up mailing all my documentation, along with a cover letter.
I was polite, and asked them for some consideration --- I expected Gold and got Platinum.
PS - I've put in over 90 nights since then, so I guess it was a pretty good gamble on their part.
Location: Back to the Buffalo. At least I'm close to Toronto.
Programs: Hilton, AA, SW, Delta
Some are lucky and some are not. We sent in everything (HHDiamond) was staying at a full-service Marriot and they wouldn't do anything. We now have over 100 nights at Hilton with only 6 at a Marriot. Give it a try with Marriot.
