Cost of tests are going to be an issue especially for families but more worrying issues are.
what happens if you or one in your family test positive in the test before you leave your holiday destination.. two weeks in quarantine there. An extra two weeks accomodation expense having to be found at the last minute so top rate. Plus missing two weeks work. Oh, and if you are lucky, you might get dragged out of your hotel by the police at 2 in the morning to be taken to a quarantine centre, for which you have to pay.
assuming we use a traffic light system like the uk, what happens if your holiday destination goes from green to orange or red just before you leave, or worse after you arrive. If it goes to red you would probably get a refund, orange, well the plane is still able to go…
and on top of that, have you had the CORRECT vaccine because some are better than others, and some are not accepted.
I can’t see international travel quickly returning while these issues exist. Which will probably be for at least another twelve months.
