The Marquis has a check-in kiosk. Assuming you would book the room, perhaps in your name adding one of the family members as a second guest, and they check in at the kiosk using your MR #, might the kiosk automatically transact this as being your room and extend benefits accordingly????

(I honestly don't know and am asking so that maybe someone else with more experience could comment. I have never used the kiosks to check in.)
