I am going to be taking a few night trains in Europe - Vienna to Prague, Prague to Frankfurt, and Venice to Paris. I am a bit concerned with the trips getting booked so I was looking at making reservations on RailEurope's website.
My only concern is whether or not RailEurope's reservation prices are the same as those in Europe. Does anyone know if I would save money if I purchased the reservations once I am in Europe? Also, should I be worried about making reservations in advance? Thanks!
