Carol - thanks, I saw that. But that answer prompted this question and if I can do a BVI test only 2 days before travel, I can reduce my tests from 3 to 1. Otherwise I need to do a free test tomorrow, a $120 test on Friday and another $120 on Saturday plus the 4-hour round trip by train for each one. While tests (both rt-PCR and quick-tests) here in Germany are free, they don't send results for 48 hours and don't work on weekends so I can't use those for this trip and need to do those special tests
