Hurtigruten is a voyage along Norway's jagged coastline. It is sometimes called the world's most beautiful sea voyage. Originally, Hurtigruten was used as a means of transportation for passengers, goods and mail along the coast of Norway. The ships still transport a limited amount of cargo, but today the ships resemble cruise ships more closely than the original coastal steamers.
The voyage is a simple way of combining lodging, eating, and transportation. A one way travel takes 6-7 days, while the round-trip takes 12. This contrasts Norway-in-a-Nutshell tours which are 2-3 days. It's also possible to purchase off-&-on tickets. Port stops vary in length. They can be as short as 5 minutes and up to 5-6 hours.
A museum, including parts and one whole, prior versions of the ship Finnmarken, sits in one port, Stokmarknes, which explains the history of the line.
Some ports livelihood revolve around the daily arrival and departure of these ships (at all hours of day and night).
The price for a full round-trip would be like the price for a ordinary cruise. However it is possible to join the voyage only for part of the voyage. The cost for a such voyage is calculated partly for the distances traveled, and for the cabins. If you would like to cut the cost. This can therefore be done by only traveling during daytime, or stay onboard only one night. Most ships are capable of carrying cars (typically 40-50, excepting the 2 oldest ships). This could make possibilities for interesting round-trip.
Sea-sickness: yes, it is possible. A number of reaches are exposed to the full force of the Atlantic. During winter, there is no assurance that any of the ferries will make it all the way to Kirkenes.

Drive back in a car. A full roundrip Bergen-Bergn with ship one way, driving one way, would require two weeks.
