Here's our situation. Two couples traveling to Germany/Austria for 16 nights in October (flying in to Berlin and out of Frankfurt). Our usual style is to rent an apartment to use as a home base in one or two locations and explore the surrounding areas, but in Germany and Austria, we think that's not feasible. My husband and I have visited many of these cities before, but our friends have only spent two nights in Frankfurt on a layover so haven't seen much of the country. Their families are from Bavaria so they want to see explore that area for most of the trip.
Please look over this itinerary and let me know your thoughts.
October 7-11: Berlin (travel to Salzburg by train)
October 11-15: Salzburg (train to Munich and rent a car to travel to Fussen)
October 15-20: Fussen (drive to Nuremberg)
October 20-21: Nuremberg (stop in Rottenberg for lunch and return car in Frankfurt)
October 21-23: Frankfurt (train to Bacharach for lunch and sightseeing on the 22nd)
The only thing we've booked is our flights and four nights in Berlin, so we're open to adjustments to the schedule.
