yep. someone will be along shortly telling you what a total security violation it is posting our layover hotel. As if anyone couldn't just stand at any airport curb for 15 min to identify what shuttle/bus took us to about 75% of our hotels. When the van driver in some foreign country, driving an unmarked beat-up van, wearing dreadlocks, sandals, and a wife-beater T-shirt, has to show us an actual ID before we jump in the van with him to go who knows where... THEN I will consider not laughing when someone seriously proposes this as a security risk.
You may not want to get all those PMs though.
