Princess has joined the group too, beginning Sept 19:
UPDATED: Will I need to have a pre-travel viral COVID-19 test performed prior to boarding the ship?
Yes, on voyages sailing through September 12, 2021, ALL guests will be required to produce a negative viral COVID-19 test (PCR or antigen) result taken within 3 days of their embarkation.
On voyages sailing September 19, 2021 and after, in accordance with CDC directives, ALL guests will be required to produce a negative viral COVID-19 test (PCR or antigen) result taken within 2 days of their embarkation. If sailing on Sunday, the test may be taken on Friday and Saturday, and as late as Sunday, if you are guaranteed to receive your results in time for check-in.
Guests will be required to provide proof of a negative COVID-19 test along with proof of full vaccination upon arrival in the terminal and can then proceed on board.
Guests who travel internationally should always ensure they understand all entry and airline requirements to travel from their home country and the destinations they plan to visit, including where health authorities may require pre-travel COVID-19 testing. In addition to mandatory pre-travel COVID tests for vaccinated guests, guests who have traveled internationally in the 14 days prior to embarkation, will require an antigen test at embarkation. For US sailings, this excludes travel to Canada.
We expect these requirements will be temporary and we appreciate your cooperation and look forward to welcoming you aboard.
