On a cruise ship, it's always been about protecting yourself...wash your hands, don't touch your face, ride the elevator only when it's too many flights of steps to walk up or down, etc...the list goes on. And I'm glad you realize for others it's their choice. Truth is, at my wife's clinic, the big issue now is people getting other respiratory viruses (especially kids) from wearing masks for 2 years and destroying their immune systems. Cruise ships have always had a higher risk for catching "stuff" than any other form of travel. It won;t ever change...do what makes you feel better/safe!
