We will be in Koblenz for a few days towards the end of May. Previous forums suggest doing a Rhine River cruise from Bingen to Koblenz but, as we will be staying in Koblenz it seems more logical to start our cruise here and then possibly catch a train back. Any suggestions? Also, the KD line information suggests we can get off at any stop. If we do so Can we then catch another KD line ship to continue our journey or do we then have to make our own way?
