Royal Caribbean made the following vaccination policy update:
"Unvaccinated travelers can join us for almost all U.S. sailings. Starting with September 5th departures, guests who are not vaccinated can sail on almost all cruises from the U.S. (except itineraries that visit Canada or Bermuda). More Details
"Testing protocols will be easier. Starting with September 5th, for U.S. cruises that don’t visit Canada or Bermuda:Vaccinated guests won’t have to take a pre-cruise test on cruises that are shorter than 10 nights. Unvaccinated guests age 5 and up will need to test within 3 days before boarding, regardless of cruise length. We will begin accepting results from self-administered home tests. See Full Testing Details"
"Requirements in other regions: Starting September 5th, guests who are not vaccinated can also sail on European cruises. Currently published testing and vaccination requirements remain in place for cruises from Australia and Singapore; cruises that depart from or visit Canada or Bermuda; and transatlantic sailings, until further notice.
