Need help with below. If I get to the station on the day of travel in time to catch an available earlier train can I exchange my ticket? (I guess probably) And at what cost (15 euro and fare adjustment maybe)? The "From two days / 30 minutes" is not clearly translating for me. Minor related question - does this fare allow use of the Voyageur First Class Lounge?
