As of now, US is requiring negative test one day before travel back to the US.  Is there any testing places that do not have to have an appt for a test near the Termini or one that I can make an appt for same.  Will be using hop on hop off, so can be anywhere along the route.   Have an early morning flight out of FCO.  Can I get tested there the day before if I show my ticket for the next day?  Online airport testing info states testing available to ticketed pssengers.  Have emailed FC
