I booked 3 "Ticket-Reservations" on June 29 on an overnight train in a 6 person Couchette. I was able to get these at a very reduced rate of US$150 (including the Rail Protection Plan). Do I need to purchase anything else to use these? It says the "Fare is Subject to Conditions", but none are listed. How do I know if I have booked the train and the Couchette or just the Couchette! I booked these directly on RailEurope. Help.
