Without being sarcastic, and/ or a wise guy, I’d respectfully say , you’d be better off staying home.
My wife, and I were on the holiday cruise of 2021 on the Ovation. Up to date vaccinations and masks were required . We social distanced , avoided crowds and ate outside as much as possible, and took all the precautions that were advised.Still, we both got Covid, at different as did many others. We were separated and quarantined. However , we’ve taken several cruises since then without masks and testing. We’re currently on day 25 of a 32 day cruise on SS. You can take all of the precautions and still be exposed.
I realize that we all have different thresholds of risks, and you need to do what you feel comfortable with . Good luck with whatever decision you decide to make. Only you can make that decision.
