This was our third Viking cruise. We were not disappointed. Seeing 5 countries in such a short time was outstanding. The choices Viking made were excellent. The staff are top notch. The food was representative of the areas we visited, had lots of choices, good taste and quality. Many excursions, included and optional.
There was an informative tour of Passau before the cruise began; including a pipe organ performance in the Cathedral. This was a must to be heard event as it is one of the largest pipe organs in the world. Great local guide, as were most (except for the one angry guy in Vienna).
Viking knows how to manage time, people, places, and spaces.
