We've wanted to visit these countries for some time and have enjoyed a Viking river cruise. In addition, we preferred to travel on a smaller ship, rather than a typical large ocean cruise ship.
The Viking Sky has a well-designed interior: the public areas, like atriums, are spacious and attractively decorated.
Our cabin, while not luxurious, was exactly what we needed, as we did not spend much time in it.
We had one of the more basic cabins; yet it was adequate for our needs, since we intended only to sleep and rest there. The bathroom was quite efficient and practical in that provided well-organized storage and shelving. The staff kept cabins meticulously clean.
