Who said the documents were false? :P

The documents don't have to have any fictional information. Not talking about a work ID or security clearance, just paperwork on official letterhead with the signature of some head-honcho giving me permission to use the rate due to my "relationship" with the company.

The fact he's never actually had to do it was my main point though - most IHG properties don't seem to care too much, although I'm sure there are those that do.
