We have been vaccinated and boosted. We went to Bermuda in May. I wore my make whenever I left my room and had my small hand sanitizer. I didn't get sick. Husband didn't wear mask. The morning of Disembarkation, he had symptoms.
I ate at the restaurants, sat in crowds and enjoyed myself. If I went to the buffet I used hand sanitizer before and after touching the tongs.
I got off the same way I got on, no covid. I suggest wearing your mask as much as you can, use your hand sanitizer and ENJOY your trip. (For informational purposes only, does not constitute medical advice).
