Ken...under the guidelines of Jamaica's Covid-19 Tourism protocols....there's a entire section devoted to being able to rent cars. The rental company has to follow their guidelines and be Covid compliant.
Jamaicajeanne....I'm not sure why MOH would tell someone they can't rent a car nor would I send an email to them asking this question....Ministry of Health says No to everything.
I'd be more inclined to email the question to the Ministry of Tourism at Visit Jamaica.com...as you've said above.
