Another why I would want COR...
In my situation, I am pretty sure that I will test negative on antigen test pre-cruise. (Have done so today and next cruise is 9 days in the future.) However, I will be traveling with a vaccinated/newly
boosted, previously uninfected individual. IF they were to be contact traced and tested positive... perhaps the COR would come in handy? If I were to be contact traced and they decided to test with PCR?
Why I would not...
It promises to be a hassle and more difficult to board with unfamiliar dock workers. It may cause issues with port shore excursions.
I really don't know what the 'right' answer is, however...if I have both, then I should be covered in all instances. (Fingers crossed.) And I could travel to/from Europe, if I were so inclined at the last minute.
