This is a unique cruise, if must be said; its strengths lie in the scenery, the food and the ability of the small ships to get into small harbours.
But beware: the value for money is NOT good. I know this is Norway, but drinks are exploitatively expensive and the trips ... eeesh. These latter are, frankly, a mickey-take.
Here are some tips:
Nice cabin close to embarkation doors but no real problem here. Cabin was compact with two fold down single berths with comfortable mattresses. Much like a standard class cabin on a good ferry.
