I have a few audits in Germany coming up the in Fall, and have some time in between to explore the area.
My current itinerary:
AMS (work trip) Sept 17-20
Cologne Sept 20-22 (weekend, work is covering $)
Frankfurt Sept 22-25 (also work covered, some touristing)
Sept 25-Sept 29 - Wurzburg, Romantic Road, etc (not booked yet)
Sept 29-Oct 1- Munich for Oktoberfest (booked, flying out Oct 1)
I will be back in Munich Oct 20-23 after I complete other portions of my travel (and other work obligations).
My main questions are - what are the best things to do/see in Cologne, Frankfurt, and between Frankfurt and Munich? Does anyone have any recommendations on what to do in Wurzburg, and down south towards Munich? I was born in Wurzburg, so I definitely want to see that city and area, but otherwise am completely open. I will have a rail pass through work, but thought renting a car might be good to see some of the smaller towns for the days I'm touristing.
I plan on avoiding Munich during Oktoberfest except for the time I will be attending Oktoberfest due to cost. I will see more of it when I am back for the work portion of that visit (Oct 20).
Also open to suggestions on where to eat, museums to visit, etc! It will be my first time in Germany since I was born.
