Carnival Cruise Line and Princess Cruises stopped requiring vaccinations for guests on most cruises in September.

Precruise testing is no longer required for cruises to Canada, Greece, and Australia, according to local guidelines.

Guests who are unvaccinated can sail with the brands, except for cruises in Australia or on cruises of 16 nights and longer, with the results of a negative test taken within three days of embarkation.

Policies are subject to local rules.

The guidelines help ensure a Princess vacation is available to everyone.

Cunard keeps vax requirement

The testing requirements of the sister brand were not changed.

The majority of sailings will see self-testing changed from "mandatory" to "highly recommended" for vaccinations. Passengers on longer, more complex itineraries will need to have an observed or in-person test with a "fit to travel certificate" prior to departure. People over the age of 16 must still be protected from vaccine.

The exception of countries where government regulations and protocols may vary is Canada and Australia.
