An experiment--showed both my Platinum Premier and Lifetime Platinum card at checkin to the associate at the Front Desk. Her response, "we have your Marriott Rewards number on file, thanks."
So, the word seems not to be getting there about recognition of usn's.
"we have your Marriott Rewards number on file, thanks."
I get that line ALL the time. A few times the FD will say, "Thank you for choosing to stay with us, we love our Platinum Elite."
