My son and his friend (21 years old) are traveling to Europe this summer flying into London and out of Amsterdam May 22 returning on June 14. I maybe should have given a bit more thought to the return city since they really want to venture down to Rome. It's a long way back to Amsterdam from Rome. I have spent several hours trying to figure out the best rail option and don't feel like I have come to any solid conclusion on the best option, passes or point to point.
Itinerary may look something like this: London, Brussels, Paris, Munich, Rome. Vernazza, maybe somewhere in Switzerland to break up the trip back to Amsterdam. Maybe time to stop in Cologne. They are young and want to see a lot while they are there, thus the number of cities. Any suggestions on train options. Read somewhere that passes may not be needed in Italy? Some passes have surcharges or limited seat availability? Thanks
