We will be arriving back in Athens from Santorini exactly 72 hours prior to our flight back to the US. I was wondering if we should get the Covid test there, rather than finding a place in the city, or bringing tests with us and possibly having to wait for someone to come online to administer the test with us. I know the test is done in the arrivals terminal at ATH. Has anyone had the test there? Is there a long wait? Thanks.
