Doing a 12 day trip in March and staying in Dusseldorf, Nurnberg, Munich & Fussen
Starting in Dusseldorf (3 nights) mainly to see a Dortmond soccer match,
Then Nurnberg for (2) nights- not sure of daytrips from here yet
Fussen (2) nights - for castles and a day to relax seeing the alps
Munich for (4) nights planning excursions to Dachau, BMW, Salzburg
Want to see Rothenburg ob der Tauber for the day and not sure what location is best of the above Nurnberg or Munich to do that. I hear it is fun to actually spend a night in Rothenberg after all of the tourists have vacated for the night?
Also not sure if I should extend the time in Munich as opposed to staying in Fussen to see the castles and just relax for a day. As Fussen could be another day trip from Munich.
Would really appreciate any feedback. Also like feedback on the length of time to get a rail pass as opposed to just purchasing local passes for some of the days.
