Staying at Courtyard in Concord, NH, I had a typed note in the room addressed to "Dear Silver Member." Aside from that, no acknowledgement or perks in full-service Marriotts in CA and BKK. Oh, and I should add that having access to a Marriott Silver Elite line allowed me to snag the last hotel room at the Marriott in Saddle Brook, NJ on March 15 when EWR was shut down due to the ice/sleet storm.
