I always wanted to go to the top of the world in the middle of winter, it was a wonderful experience.
This is a once in a lifetime trip to see the northern lights, and also experienced complete darkness for more than a week while above the Arctic Circle. The restaurant staff and the food were excellent, especially the ice cream, it was to die for. I felt that the excursions were well overpriced, as are most things in Norway, but Norway is an absolutely beautiful country which should be a must on anyone's bucket list.
Hurtigruten certainly provide a comprehensive encounter of the country from the ocean side, they provide a wonderful service up and down the coast, not only for tourists, but also for the population by providing a very efficient transport service for the people and freight.
Cabin was fine but the cleaning staff left a bit to be desired.
