COVID-19 canceled your cruise. Here’s how you can use that money for a future vacation Michelle Marchante It looks unlikely. Many cruise companies, including Florida-based Carnival Corp., Royal Caribbean Group, Norwegian Cruise Line Holdings and Disney Cruise Line, have continued to cancel trips as they work toward the Centers for Disease Control and Prevention's 40-page conditional sail order. The order requires the companies to meet certain COVID-19 safety benchmarks — including testing for all passengers and crew on embarkation and disembarkation days — before they can set sail. The CDC also has a Level 4 travel warning in place for cruises — its highest level.
