We had already done 2 Viking River cruises and enjoyed them so much, we decided to do another one. This one may have been our favorite. The first two cruises, we did with another couple, but this time it was just the two of us, and because it was just the 2 of us, we made a better effort to meet other people. We met the nicest people on this cruise and always had other people to eat meals with or sit with in the lounge. Alan was the cruise director and was absolutely wonderful- can’t say enough good about his personality, organizational skills, just everything. Hotels in Prague and Berlin were very nice and well located. All the included excursions were excellent and the 4 optional ones also were as well. I do think the optional excursions are awfully expensive though. As usual, the ship was spotless, staff exceptional and food wonderful.
