The service, the meals, the staff, and the ship itself were all first class. We especially enjoyed all the destinations where the guides on shore were knowledgeable and friendly. The cruise director was really organized and gave us a good preview of every stop on the beautiful cruise up the Danube and Rhine toward our final destination, Amsterdam. Our two on-shore stays in Budapest and Amsterdam were also outstanding with the help on the Viking representatives on-shore. I would recommend this cruise to anyone wanting to see Europe on all its beauty and interesting culture. The entertainment on board was also very interesting and fun at times. No negatives at all from either my wife or myself. We enjoyed meeting the other passengers on board and I enjoyed being able to walk and run on the upper deck walking path.
