It isn't interesting to make a Rhine river cruise from Cologne to Koblenz (Coblence) or back
Better, faster and cheaper on the first day to drive from Cologne to Boppard on Rhine river with train: www.loreleytal.com/links/eisenbahn
your Half day Rhine river cruise in Boppard on the Rhine ...
On the second day with boat from St. Goar, Oberwesel or Bacharach to Assmannshausen or Rudesheim on Rhine river. Schedule and prices
The Rhine cruise from Rudesheim to Mainz is not so interesting, because the Rhine is not hilly and there are no castles to see from the riverboat.
Drive the next day every hour with train from Assmannshausen or Rudesheim to Heidelberg
on Neckar River
or to the castle hotels on the Neckar river www.german-castles-road.com
