Bottom line up front: Avoid Hurtigruten Cruises (and any of their ships including the Midnatsol) if your aim is to go on a "once in a lifetime" type journey. You will probably be disappointed.
We traveled on the Midnatsol in Oct-Nov 2019 for a Southern Hemisphere Adventure cruise that was supposed to take us from Montevideo (Uruguay) to Patagonia, Falklands and Antarctica before returning to Ushuaia (Argentina). Everything was booked through Hurtigruten travel based in Seattle, WA, a year in advance (Aug 2018). Hurtigruten still managed to mess up majorly in several ways! In this post I'll detail several things they did that spoiled what was supposed to be a memorable vacation.
Context: This was booked as a once in a lifetime experience for my 70-year old mother and me. My mother suffers from a rare and terminal illness which is currently managed and expressed a desire to see the frozen continent before it was too late.
