Hmmmmm. All I got was a little metal luggage tag and a personal rep..
I take that back. I did two personal trips, One to JazzFest and one to Key West. Both times I used the personal rep to book and both times I got crazy nice rooms. Presidential suite in Key West.
When I book online (like 99% of the time), I get the standard, 'Thank you for being a Platinum member'. Which is fine. Next time I go out of the country, Ill have my rep do the booking and see if I get the star treatment. In my experiences, international sites kick it up a notch for Plat, PP and Plat for life.
Side note, I was also quoted the 'top 1%' by Marriott on the phone.
