An excerpt from Cruise Hive:"All guests not vaccinated, including children, will need to be tested onboard. Carnival will add $150 per person to guests’ accounts. This testing does not include the mandatory negative test result that guests have to show before boarding the ship but is for a test during and towards the end of the cruise.
Thanks for the clarification. So ... a lot of fol-de-rol to appease the commies. Cruising was fun while it lasted.
As a test, I think a couple of the lines should offer cruises for only non-vaxxed people. It would be interesting to see how that would be received.
