The test sailing will aim to put into practise new protocols which the cruise line has come up with in line with the latest CDC guidelines to help prepare cruises for a return to sailing in March. Protocols being trialled include testing both onboarding and during the cruise, as well as isolation protocols and tracking passenger symptoms. It is not yet known how many volunteers will be selected or when the test cruises will run. The destination of the trial cruises is also not yet known, though passengers are likely to enjoy the full holiday experience, including onboard activities, dining and a stop at Royal Caribbean's private island CocoCay, according to Good Morning America.
