I doubt they'll print an extra booklet for a single person. You could just photocopy the directions from one of the booklets.
You automatically receive 2 DME luggage tags per person. If you need more, you can request more. DME will transport all checked bags that were checked with your airline. In other words, let's say one person checks 5 bags (and pays the extra chargesto their airline) ... if that person requests extra DME tags, that person will have all 5 bags automatically handled by DME, at no extra charge by DME.
