In October I was on the round trip Bergen-Kirkenes-Bergen Hurtigruten cruise on the MS POLARLYS.
Some observations about booking via Hurtigruten US. They are just a booking agent for Hurtigruten Norway and they don’t really know the details! Some examples, we booked one of the few Arctic Superior rooms with two lower twin beds. We had seen the cabin plan on the website but it wasn’t the same when we arrived. Our assigned cabin had an upper and lower bunk bed. When we complained to the onboard reception manager she said we got what we had paid for! Apparently the cabin plan online was inaccurate. She said she would try to accommodate us but it could cost us more money! As it turned out we had the option of selecting another cabin with two lower beds and we are supposed to request a refund from the US agent because it was a lower class. We’ll see how that works.
One of my friends had told our booking agent that he is a vegetarian. Didn’t matter. If you have any dietary restrictions you need to tell the head waiter once you are on board. After doing so, the staff were extremely accommodating.
If you book the 5th deck, be aware that there is a walkway around the deck. The windows are designed so that someone can't see in during the day and can only see in at night if a light is on in the cabin. Not for everyone!
