After checking the Lander maps, I have not been able to find a Lander ticket that would cover going from the Rhine Valley (Oberwesel) to Wurzburg. Bayern and Baden Wurttenberg cover Wurzburg, but not Rhine. Rhine-Palatinate cover the Rhine, but not Wurzburg. Do I have this correct?
I assume an advance purchase of a specific train is the best option for my family of 4? Would prefer not to be tied down to a specific train time.
Many thanks!
