I think there is a distinction sometimes between how it is handled with tour groups vs. master billing although I haven't been on a tour group in many years -- that's just what I see from my observation, organizers in the lobby handing out keys.

Master billing will usually have your name as you go to the desk to check in. But ... I'm skeptical that the meeting folks I deal with have readily available reservation numbers and wouldn't bug them about it. Marriott, Hilton, Hyatts all have my name, I give them my number, they usually give me the appropriate benefits of status Sometimes I get points/nights credit; sometimes I don't. Nights credit seems to happen sometimes when I give them my number and make incidental purchases during the stay. I always get points for the incidentals but usually not for the room rate.
