I recently signed up my company for this as well. I'll be using the first rental with it this Saturday, but I was wondering. As a #1 Gold, do I have to show my business card to anyone to "prove" that I work for my company that's assigned the CDP #? Are we able to provide the CDP # to friends so that they get the discount and we get the free rentals (since I'm the head of the program) or do they have to show a business card or other proof working for my company. Just wondering anyone's experience with that. Thanks.
