Great ship, good service, excellent food. Mediocre entertainment
Due to water level we did not complete our river journey, we were offered bus trip to Nuremberg from Passau (3.5 hours one way). Other ships transferred their passengers to another vessel in Regensburg and continued on to Nuremberg. We were not offered a refund, even that we booked a river cruise not a bus tour of Europe. We spent three nights in Passau.
A side activity to see Figoro's wedding at the Vienna opera; we were taken to a secondary venue, and played by a second tier cast (Little misleading, since we paid full price). Other ship's passengers got to see it in the opera house.
