I've been reading responses to other inquiries and it has helped me (I hope) fine tune my own plans for Cologne, but I do have a couple of questions.
I originally thought we would take the train to Bacharach (from Cologne) then take the boat to Koblenz and train back from there.
After reading advice given to others, I now think we may take the train to Bingen (is Bingen (Rhine) the correct rail station?). And then take the boat up to Boppard, then train back to Cologne.
But someone else mentioned Rudesheim...would I miss a lot by not going that far?
When we were in Munich last year we made extensive use of the regional Bayern ticket. Is there one like that covering the itinerary I planned? We will be doing this on a Sunday in June if that matters.
