Hello!
There are four of us and we are trying to determine if the trip would be better by rental car or by train. The trip will begin in Nice, FR and go to the Swiss Alps for 4-5 days (where we will stay in the Lauterbrunnen Valley region), then to Southern Germany for 5-7 days where we will plan to do day trips to historical destinations including castles (Black Forest or Bavaria), and then to Paris.
The cost of the car will be more, but it's ok. What will make for the better quality trip?
Thank you!
