I wanted to cruise the Norwegian coast and Hurtigruten provides a very safe experience. We were told if the weather is really bad, they ships wait it out until it's safe to proceed which is nice to hear after the Viking disaster.
The cabins are small but adequate. I travelled with a friend but we chose to have separate cabins. 12 days together in one small cabin would have been difficult.
The pace of the cruise was perfect and there were plenty of opportunities to get off the ship to explore even when the stops were short.
