In the US the requirement for all of the chains is supposed to be that they have to have permission from the person whose name is on the reservation to let you check in. Usually this is in the form of putting their name in the also travelling with field or similar. I usually work in the summers as an umpire for softball tournaments, when I travel, the Tournament Director is responsible for setting up the hotel rooms. Every time they have not allowed me to check in until I knew whose name the room was under and verified that either my name is listed in there somewhere or verified by voice that I was allowed to check in.
