I agree that the Marriott people are usually the best. I'm Diamond with Hilton and Platinum with Marriott with a total of around 170 nights a year. I always get my 60 nights with Hilton and try and give the rest to Marriott. Sure, I have issues with Marriott but overall I think they offer the best and most professional service.
I have 8 free award nights coming up in Paris and Nice. I'll let post what kind of luck I have with rooms and whether or not suites were involved.
