Royal Caribbean and Celebrity are to allow unvaccinated guests onboard more sailings from 5 September.

They will be able to sail on all RCCL cruises from Europe, Florida, Los Angeles, California, Galveston in Texas and New Orleans.

They will also be allowed on Oasis of the Seas from Cape Liberty in New Jersey.

Celebrity Cruises said unvaccinated guests will be allowed on all cruises except to Canada.

Unvaccinated guests aged five or and older must still test before sailing with Royal Caribbean, but can do so up to three days prior to embarkation, regardless of the length of the cruise. Self-tests will be accepted.

Unvaccinated passengers on Royal Caribbean’s European cruises must also take a COVID onboard their ship before disembarking into Spain or Greece.

Celebrity said unvaccinated guests aged five and over will have to self-test for US cruises, while those aged 12 and above will have to test on select European sailings.

From 5 September, fully vaccinated guests will no longer need a negative pre-cruise test on any sailing of nine nights or less with either cruise line, unless visiting Bermuda or Canada.

All guests, even those who are fully vaccinated, must continue to test before any cruises of 10 nights or more.
