"Guests who do not provide documentation of full vaccination will be considered unvaccinated and will require a Covid test at the terminal at their own expense. Guests that do not meet the requirements will be denied boarding."
So if you're not vaccinated they require you to take a Covid test at your expense or you can't board. It's left unsaid whether meeting "the requirements" means testing negative.
And if you test positive on the ship likely disembarked for quarantine, depending on the requirements of the country you're lucky enough to be in. My guess, Florida and Texas probably have quarantine requirements as well. An uncomfortable and risky form of travel for the unvaccinated.
“” It’s left unsaid whether meeting “the requirements” means testing negative.””
And if you do not have your vaccination papers, you have to wear a mask anytime you are out of your cabin.
Why not just tattoo the un-vaxxed with a 666?
