Hello, I will be in Dusseldorf on May 19th, then taking the train (probably) to Bavaria. So far I am interested in visiting Bamberg and Nurnberg, neither of which I have visited in past, and revisiting Regensburg (which I loved) and Munich. (I have already been to Fussen and the nearby castle, and along the Romantic Road). Do you have a suggestion as to where to spend most of my time? My interests include post-impressionist art (like the German expressionists), opera, classical music, history (medieval; WW1 and 2), architecture. I also enjoy bike-riding. I will probably fly home from Munich but I can still change that if there is an easier airport. THANK YOU!!!!!
