There are a couple of other threads where this was referenced. I know when I walked into the Concierge Lounge at the Queens Park Marriott, I was greeted by name. Additionally, on the second day, they brought a coffee to me that was identical to the one I had the day before. I've had similar service at a couple of Marriottts in London (well not the coffee). This is not unique to Marriott, Mandarin Oriental and Four Seasons also do this with regular guests.

Its really a factor of an engaged GM. I don't think Marriott is passing pictures around but there are certainly GM's who understand the importance of service.
