This is what I intend to do:
After arriving ZRH, we’ll take the train straight to Geneva. Then from there, we make our way back to Zurich where we fly out again.
I am planning on visiting the following places:
Bern, Interlaken, Grindelwald, Lucerne, then Zurich.
If I’ll be driving, should I rent in Geneva and return the car in Zurich at the end of my trip? Or should I rent a car in each city and take the train between cities?
