I'm fully vaxxed (5 shots). I've been on 5 cruises since the restart...only wore masks on the one that required it. Came home with Covid last August after an Alaska cruise.
I will wear a mask on my flight to a cruise, but only because I don't want to have covid on the ship. I won't wear a mask on the ship or on the way home. Just like I won't wear a helmet AND a seatbelt when I drive.
Between the weakened variant and available antivirals, this certainly isn't the 2020 covid.
