Yes, I would have no problem doing this. As others have said, many countries require proof of vaccination for travel and currently many of the islands DCL sails to require negative PCR tests in order to enter the country. The Bahamas, specifically, has been very strict about testing and even closing its borders. I don’t think it’s out of the realm of possibility that either proof of vaccine or a negative PCR test would be required and given DCL’s large investment there, if they want to sail again, they’d have to comply.
