Ok, I would like to get information for this booking, before I make a mistake. I have the twin German rail pass and we are wanting to travel on the CNL from Munich to Hamburg. I hear the berth compartments fill fast, so I plan to book an Economy Double before we go. When booking it shows where I can book as supplement only. That is what I need to do since I have the pass, correct? Do I also need to reserve a ticket for the train, or is the supplement and pass all I need?
Thanks
