Tampa here. I am also sailing on the Explorer OTS, March 27 from PR. Myself and everyone else sailing along, have been VAX'd and Booster'd, however, between now and March 27, RCL and/or PR Gov., may create new protocols in order to sail. I am wishing all this COVID crap will be subsiding a little and we will be able to still sail. Who knows, but we have two months to wish for the best. Happy and safe sailings everyone. Tampa Cruiser.
