"What cruise can you go on unvaccinated" refers to cruise lines that do not require passengers to be vaccinated against COVID-19. An example is the Carnival Freedom, which sails from Port Canaveral, Florida, to the Bahamas and other Caribbean destinations without a vaccine mandate.
Unvaccinated cruises are relevant because they provide an alternative for individuals who are unable or unwilling to get vaccinated. They also offer a more relaxed and carefree vacation experience, as passengers do not have to worry about vaccine requirements or testing. Historically, the lack of vaccine mandates on cruises has been a controversial topic, with some arguing that it puts passengers and crew at risk and others maintaining that it is a matter of personal choice.
