This thread reminded me of my front desk training years ago... I worked in both Hilton and Marriott properties. The Marriott training specifically covered walk situations. I don't recall it even being mentioned in the Hilton training.

There is actually a status level less likely to be walked than Plat at Marriott, incidentally. It's honeymoons. Very, very specific training that under no circumstance do you ever walk someone on a honeymoon. And also never walk elite members. But definitely not honeymooners.

(This was humorous at the time, since few people honeymoon at rural Residence Inns... but I suppose it was possible. Tell you what, if anyone ever decided to, they definitely would not be walked.)
