In the last 20 or so years I've been "sick" only two times: Once during a cruise, once just as the cruise ended. I would def cruise again, but I'm gonna need a vaccination for covid.
During the pandemic I've been to a wedding, a couple of funerals (not covid related), grandkid's birthday party, and out to lunch in restaurants a handful of times, and spent a week at WDW with no ill effects. I guess because I got sick on previous cruises way before covid was a thing makes me a bit gun shy for the time being.
