I’m traveling with my 14-year-old daughter from Paris to Interlaken on July 11. We have the 4 day, 1st Class Eurail pass. This will be our first trip using the pass, and I’d like to book the trip below. Reservations are required for the first leg, and optional on the last leg. I worry about the stops in between. What if the trains are full? Or, is there a pretty good chance we’ll be able to hop on and find a seat?
