I received additional information. A test is required within 5 days. That means if your BVI trip is 9 days or less the day 4 test covers you. Sadly our trip is 10 days. We are all going to get a antibody test now on the hope we are positive. I had covid and all but my granddaughter are vaccinated which may trigger a positive antibody test. They do expect there may be some relief in the covid test for vaccinated people in the next two weeks.
