Royal Caribbean has announced a return to cruising in June, but not for everyone. The cruise line, as well as sister cruise line Celebrity Cruises, will require COVID vaccines for all adult passengers and crew members. Passengers under 18 will be required to provide a negative COVID-19 test.

Royal Caribbean also extended their suspension through May 31, 2021.

Royal Caribbean’s Adventure of the Seas will be open to adult passengers, sailing out of Nassau, the Bahamas, starting on June 12. The cruise line expects to operate the ship with 100 percent capacity.

Royal Caribbean will also be launching service for Quantum of the Seas in Singapore and Odyssey of the Seas in Haifa.

The company has announced schedules for the three ships through August.
