My husband, teen daughters, 70 something in-laws and I will be traveling to Germany this summer. Our must-sees in Germany are Bad Mergentheim (west of Rothenburg, grandpa's birthplace), Rothenburg, Neuschwanstein, Munich. We also plan to visit Salzburg, Berner Oberland and Paris.
Out initial itinerary is Frankfurt Airport - Bad Mergentheim - Rothenburg - Neuschwanstein - Munich - Salzburg - Berner Oberland - then train/plane to Paris.
Would a van or train be the best choice for the six of us in Germany, Austria, Switzerland?
Would turning in the van sooner and taking train from Munich or Salzburg to Berner Oberland be a better choice than making the long drive?
Would doing this in reverse order be of any advantage?
Other input?
