The sad fact is that Covid is still with us. Folks smart enough to be fully vaccinated are probably safe from serious illness, but crowds (such as cruises) are virtually guaranteed to produce some spread. My step daughter got infected two weeks ago (probably at a wedding she attended) fully vaccinated, but still experiencing flu-like symptoms. We are going to continue avoiding such locales for the time being - cruising is not the only travel option, and the measures still in place have negative impact.
