This was our second cruise having cruised the Rhine in 2019 with Viking. We wanted to start further east and travel back towards Germany. We were well informed, before the cruise, about the water levels of the Danube and if it hadn't rained how the cruise would be handled. Luckily it rained and the river was fine. The service on board was excellent, the food was always of the highest quality, featuring dishes from the area we were traveling through, and they were served by tremendous wait staff. The lectures on sights we would be seeing the next day were very informative and set the stage for the next day's events. The tours were high quality with excellent guides. The weather was fine, and the optional tours were very good and well worth the cost. The extension in Nuremberg was wonderful and a real value-added option. The tours and extras were fantastic. This was a real winner, and I would recommend it highly to anyone.
