took the KD Boat from Mainz to Koblenz. Got the 8:45 am in mainz with very few people. Had breakfast ( scrambled eggs and local ham) on the boat before it got crowded. Saw all the World Hertiage sites from the top deck as more and more people got on. Many got on in Bachrach and then off in Rudesheim. Got to Kobelnz by 2:10 pm with enough time to take our bags to the hotel, go to the train station and go back to Marksberg castle for the 5pm tour. Could have done the same short train trip to any of the villages along the route. Saw the whole world Hertiage site and marksberg all in one day!
