I work for the federal gov't and when I travel, I am required to put air and hotel charges on my gov't issued credit card. However, I am not required to put food on my gov't card. Does anyone know if it is possible for me to use my Hilton Amex in a hotel restaurant while staying at the hotel and still get my Gold 25% bonus even though my room is on another card? Has anyone tried this or something similar? Thanks.
