Solely because of the itineraries and the size of the ship. We had always wanted to visit Norway, the islands of the North Atlantic and Iceland. The two back to back cruises provided a wonderful introduction the the geography and history of this part of the world. The insight into Viking history and culture was especially interesting.
The ship was very comfortable and the hotel staff were excellent. Unfortunately we found that the reception staff, although uniformly charming, often gave conflicting information, especially about excursions, The English language skills were sometimes poor. This led us to be stranded in Bergin but fortunately the tour guides saved the day.
The majority of the excursions were excellent but the practice of putting the minority non-French speakers at the back of the buses with variable methods of delivering an intelligible commentary became a little tedious.
