We will be driving 4 days around Rhine valley, Black Forest then going to Murren for 5 days. My thought is drop car at the border and take trains in Swiz. Would I be better off dropping car at border town (which one?) and using Swiz Pass or dropping car at Interlaken (or ?)and then taking train system? From Murren (via train?) 3 days in Bavaria and Tirol area (with car) and then final 4 days in Munich. Arrive & depart Frankfurt. Or just keep car for entire 3 weeks? Any insights, thoughts, suggestions are appreciated.
Danke, grazie, spacibo, muchas gracias, domo aragato, merci, - you get the picture.

10SPLYR,

We're picking up a rental car next month in Mainz, Germany and dropping it off in Freiburg (near border), then on to Switzerland on the train.

While it would have saved money to keep the car the factors that caused us to switch to the train included: desire to have relaxed view of scenery in SW without hassle of map following and driving; and knowing that you DO NOT need a car in the Bernese Oberland.

We are traveling back to Germany after SW and picking up another car in Lindau to travel the Romantic Rd and back to Mainz.

BTW, we have purchased a Swiss Card for the SW train travel. Hope this helps.

transborder car rentals are very often very expensive and most rental companies do not allow this. The best deal is always, if you can return the car at your start location (all other rentals are subject of an extra one way rental fee).

Tom is right. That's why we have chosen to pick up and drop off rental car in Germany. The one way trip does NOT involve extra charges because we are not taking the car across the border. We're using AutoEurope.

This is a tardy, although still sincere THANKS for your info. I am spending too much time working!
