We purposely chose the explorer suite for the comfort it offered plus the use of our deck, watching scenery along the the Rhine river valley. Both ships were as nice as our previous cruise down the Danube and the crews on the two boats were pleasant and professional. I think we were disproportionately punished though, by all the time we spent bussing from Cologne to Strasbourg without having stopped in Koblenz or Speyer.
I served in the U.S.Army, stationed in Nuremberg and Frankfurt in 1970-1972. I was particularly looking forward to revisiting Heidelberg on my cruise. I knew there was more to the city than the castle. I think had we not had to bus all the way to Heidelberg from Strasbourg we might have had more time to spend in this old university town.
By the time we reached Breisach am Rhein we had spent so much time on busses we passed on the Black Forest bus trip and spent the day in Breisach and enjoyed a few hours in the village and our deck.
