@Outbound suggested the following at the other thread and I agree as a start-up plan : and I quote"
" .. Arrange accommodations for a place that allows no-fee cancelations as late as possible, with potential stay starting on the day you are supposed to depart for US. US policy is that you need a negative test three days prior to the day of departure, which effectively means four days before the day of departure. The CDC webpage gives the example that a person due to depart on a Friday can take his/her test as early as the Tuesday before. Take the test as early as possible. If you test negative, cancel the hotel reservations. If positive, then you'll be staying a while longer. "
