This was our first "post-COVID" cruise after several others being cancelled, so we were somewhat apprehensive how things would be onboard. For us, it was no problem, because what we like is being outside. So, we wore a mask anywhere inside on the ship outside of our stateroom, but being fully vaccinated and boosted, we did not while outside. We started cruising with Norwegian for the Freestyle dining - i.e., we don't like formal sit-down dinners, prefer the buffet. So on this trip, we would wear our masks, get our food, go to the outside tables to take our masks off and eat.
Our main activities (other than eating, of course!) are walking the Promenade, and hanging-out at an outside table working on a project (be it a game, journal, whatever). We avoided most of the indoors entertainment, and wore our masks on the couple that we did attend.
We were not the only ones wearing masks, so we never felt out-of-place amongst all the people - We just followed our own protocols, happy we did, and happy it didn't really impact the cruise for us.
Cabin was great! Bedding was very comfortable. We loved having a balcony. Only comment: We had a connecting door and a neighbor with a persistent cough in the morning. Next time, no connecting door, and fingers-crossed for quiet neighbors!
