I'm a Canadian who just returned from a 9 day cruise on Royal Caribbean's Adventure of the Seas on Saturday. My spouse and I are double vaccinated with 2 boosters. We had a negative PCR test upon embarkation. On the day following the cruise, we discovered we had an unwelcome souvenir from our trip. We both woke up ill and using a home covid test found we both had covid. After dodging the bullet for 28 months and taking a chance on a twice delayed cruise booking, we got nailed by the virus
