I'd like to make a booking - probably using AGR points - to have 3 adults in a bedroom. From what I've read on this board, I think it is a valid amount for the bedroom. However, with the size of the 3 adults I'm referring to - me included - I know we could never get all three of us to sleep in the bedroom. Maybe the one in the upper berth but not the two down below. So the question is, could I book the three of us into the bedroom where we'd sit during the day and get the meals, and then have the youngest and most able among us go sleep in the sightseer lounge car overnight? I'm assuming he couldn't go into a vacant coach seat to sleep. Another question might be if he could be booked into into the bedroom with the AGR points but also buy him a ticket for coach so there would be a reserved coach seat to sleep in at night? This would be for a LD train. Comments? Suggestions?
