To me, the $10 credit per person per day is inappropriate unless the room rate is twice as much for two people as one and both room occupants are elites who would be entitled to the credit on their own. If it's one room, one elite occupant (regardless of the total number of occupants) and there's no extra higher rate being paid for the additional occupants, I think there should be only one credit per night per elite-occupied room (and it should be somewhat higher).
