Let me get this straight. So my brother that works for a Sheraton in the UK, for example, will need to provide his HR all the names of the people in his immediate family (including me) and when I tell him that I would like to book a hotel in say, San Francisco, HR would then be able to present to me something that would allow for me to check-in in San Francisco without him being there? What if there are time constraints that would now allow me to get this original document from him? I would think a faxed copy would not work? He's trying to get a hold of his HR and it seems a little hard, because he works nights. Therefore any help here would be great.
