We are visiting Germany in August. We are a family of 4 (my husband and I are in our mid 40s and our children are 11 and 8.) I would love suggestions on our travel plans. We are experienced travelers and I have driven in Germany before. We are visiting a family member in the Kassel area so we are trying to work around this meetup. The actual meet up day can be flexible but as of right it is day 3. We are struggling with days 3 -5. I have been to rothenberg and remember liking it but this was almost 20 years ago.
Day 1 arrive Frankfurt, pick up rent a car and travel to St Goar or Boppard.
Day 2 explore the area. Home base remains st goar or boppard
Day 3 drive to Kassel and then drive to rothenberg for night
Day 4 explore Rothenburg in morning and drive to Nuremberg
Day 5 explore Nuremberg
Day 6 drive to Berchtesgaden but sleep in Salzburg
Day 7 explore Salzburg
Day 8 drive to munich. Return rent a car in Munich. Spend day/ night in Munich
Day 9 Munich
Day 10 fly home
Thanks for your input.
