I haven't decided on whether to rent a car vs. training, but I'm curious, if I were to rent a car in Germany, can I take the rental car to Switzerland and/or Austria?
If so, has anyone tried to drop off the car in another country? Is it even possible, or expensive?
I'm trying to decide whether we will try to train in between:
Frankfurt - Romantic Road - Neuschwanstein - Innsbruck - Salzburg - Vienna
