Low rainfall in Germany and low water in the Rhine river means Avalon busses you close to four hours a day for the cruise days scheduled for Strasbourg to Rudesheim and Rudesheim to Koblenz.
Non stop 3 hour rides have ruined an otherwise pleasant and interesting trip.
The low water issue is ongoing. Be informed. The information packet in your confirmation of your reservation mentions the alternative of being bussed and put up in a hotel courtesy of Avalon. In fact they will drive you hours back to the ship only to drive the same route the following day - in addition to the drive required by excursions. Again,non stop.
