Great cities, fantastic food, colorful and very informed tour guides, and extremely friendly fellow travelers. Only disappointment would be selection of items on german themed dinner night.
Optional tour of Schönbrunn Palace had to little free time to explore palace grounds and gardens.
This was our first cruise with Viking and we are already recommending it to our traveling friends. We did meet many new people all of whom were native English speakers. We have continued to have contact with many after our return. We partially attributed this to the small ship size (169 passengers).
