Sky Princess, Gravdal, Lofoten Islands, Norway, day 10 of 14 nights...
Masks now compulsory inside, except when sitting to eat or drink, and outside in 'large' (number unspecified) groups.
Not surprisingly, rules change on board not just pre-departure.
Covid possibly propagated more because of the large number of passengers inside on this cruise to the cold climes of the Arctic Circle.
Also, despite recommendations, until a couple of days ago, only a small minority of passengers were wearing masks in for example lifts and the theatre.
