Our next cruise is this summer on the NCL Prima starting in London (Southampton) and ending in Reykjavik, with an overnight there before disembarkation. Other ports are Amsterdam, Bruges, 3 ports in Norway, and 2 more in Iceland before Reykjavik. The second sea day is between Norway and Iceland and will be on our wedding anniversary.
I should add that we missed out on a Princess Norwegian Fjords cruise in 2020, and will be getting to some of those missed ports this time.
