My husband and I have 14 days to spend travelling around Germany preferably using rail (as we find this the most convienient). We will be leaving the Hague on the 1st of October and need to fly out of Hamburg on the 15th of October back to Australia. I would like to see old towns, castles, the black forest and the historic areas of Berlin. My husband's only must do is the Porsche Museum in Stuttgart. I thought about dividing time up between Stuttgart, Munich, Berlin and Hamburg but then realised that it will be Oktoberfest and that it may be too busy in Munich (and we are not interested in beer). We are both mid 50's and fit, happy to walk or hike. Money is not a real issue and we are happy to do day tours. I am looking for suggestions and some general guidance please.
