Effective for embarkations on or after Thursday (4 August), fully vaccinated guests will no longer have to take a pre-cruise test on cruises with itineraries five-nights or less.

Pre-cruise testing for itineraries six-nights or longer can be conducted three days before departure and there will be no in-terminal testing for unvaccinated guests on day of departure.

However, all unvaccinated guests aged two and older must provide proof of a negative result of a lab-administered or supervised self-administered antigen test taken within three days before embarkation.

A spokesperson for the line said: "We remain, as always, committed to the health and safety of our guests, crew and the communities we serve.

"These changes will be made in phases, with the first of these updates effective on 4 August and focused on short cruise itineraries of five-nights or less. More changes will be announced shortly and all changes are subject to any requirements of destinations on the itinerary."
