My guess is I was picked because I was a member of their frequent flyer/stay programs.

I remember in the Marriott one they had everyone go around the table & mention # of nights/flights type things. I was actually on the high end & for some reason felt a bit embarrassed about it, so mumbled my reply & they thought I hardly had any, and then of course I wanted to say no I travel a lot LOL. Can't remember if Hilton had us do that or not, and a couple of times on the United one.

I do know on all that you still have to answer questions/fit into certain criteria to actually be picked for the focus group.

Cheers.
