Marriott requires that you be an actual government employee, so it is unlikely you'd get the gavernment rate in the situation you describe. My husband has a CAC card (contractor) and orders from the Army (a PDF file with a seal which he prints out and carries with him) for every trip he makes. The orders state his departure date and city and his return date and city, as well as the fact that he is entitled to government rate and discounts on travel for the trip and the military bases he will have access to on the trip. Not good enough for Marriott, he is not eligible for the gevernment rate.
