Depends on the hotel policy. Usually you get charge for extra head since it is a room for one. Except if you're VIP then you'd be allowed to bring people free of charge.
Whatever happens depends on the rules and policy guiding the accommodation of guests in the hotel.
reserved room double or single?
are the two guests have any kind of relation family, couple, friends.....?
if the room is double and, they have relation no problem at all. the one who reserve the room will be in charge.
I approach them nicely and explain the policy, ask them if they want another room for couples.
It appears in the guest list as an increase, the reservation must be modified to a double room
