A year ago, if you had asked Morgan Hines, a USA TODAY reporter, if she would have felt safe on cruise ship, the answer would have been "no," especially after months of reporting on COVID and the cruise industry. But when she found herself in that exact situation last week, she was surprised to find that she – and some others I spoke to on the ship – were less concerned than if COVID-19 had been in their backyard. Morgan was on board Royal Caribbean International's Adventure of the Seas cruise ship when six passengers had tested positive for COVID-19, first with antigen tests and later confirmed by the more-reliable PCR tests – four were vaccinated, and two were unvaccinated children. The six passengers who tested positive and their traveling parties were sent home via private transport provided by the cruise line at no cost to them. With the delta variant spreading rapidly across the nation and the world and breakthrough cases, Morgan was nervous, but those fears dissipated once on the ship.
