I too was on this voyage and it was great to see the pictures from Tromso onwards. I say that because on the Monday morning I tested positive for Covid and spent the whole of the second half of the voyage in my cabin, not allowed to leave. So glad I had a balcony, I would go stir crazy in an inside cabin.
Incidentally I share the pain of those passengers unhappy about the 'second days' in Tromso and Narvik. I took this up with Cunard before we set sail and told them that the ship's itinerary was far from clear. The Cunard website stated that they were still building the list of tours available for the 'second' days right up to sailing time. They stated that because the ship was in port past midnight it had to be listed as an overnight stop. They didn't seem interested in that an overnight stop implies waking up in the same place you went to sleep. I asked them why they hadn't put an extra element on the website for those second days stating 'sea days', in the same way the cruise-by in Romsdalfjord was an extra item for the same day as Andalsnes. I did get a sort of apology but it really is not difficult to make this abundantly clear on an itinerary. I was so glad I checked the port websites before booking independent second-day excursions.
