Is it much trouble to connect (while carrying some small luggage) from the standard trains to the trains that go along the Rhine? Considering money and even time (we would like to have as much time in Speyer as possible), would it be best to take a train the whole way, or try to incorporate a small boat segment also (say from Sankt Goar to Bingen)? Are the boats vastly superior to the train? We are looking at the KD Rhine, but is there another line that may be more suitable? We are a young couple and keep seeing that this is very popular with senior citizens, am I just being silly or could be end up completely out of place and bored? Where would be the best place to star, Bonn, Coblenz, another city?
Basically, I heard about this part of the Rhine some time ago and it seemed very special. When I saw that it was more or less on the way from Amsterdam to Speyer, I wanted to make it part of our trip. Does this make sense, or am I just stretching a day too far? thanks for any help!
