SANTA CLARITA, Calif. (CNS) — Princess Cruises has lifted its requirement that guests must be vaccinated against COVID-19 for most voyages of less than 16 days.

The Santa Clarita-based company also announced that starting Sept. 6, vaccinated guests sailing on voyages of less than 16 days will no longer have to test before boarding. Unvaccinated guests, or those who do not provide proof of vaccination, will self-test within three days of sailing and upload proof of a negative test before boarding.

The new guidelines, announced Friday, apply to itineraries from all departure ports except where government regulations and protocols may vary, such as Canada, Greece and Australia.

Guests sailing on voyages 16 nights or longer, or sailing on full Panama Canal transits, trans-ocean and other specific itineraries, need to take a supervised test within three days of embarkation (for guests 5 and older).

“These updated guidelines help ensure a Princess vacation is available to everyone,” said John Padgett, president of Princess Cruises.

The updated guidelines are subject to the local regulations of applicable home ports and destinations.
