It is my understanding that rapid tests are now being performed for arrival tests (at least for arrivals into EIS) - results within 30 minutes. Others will likely chime in on this along with info on quarantine locations. Not sure how they are handling it now - previously you would quarantine on your boat at the dock if some tested positive (all members of the group Q together).

We have traveled to the BVI twice this year - it was well worth all the hoops we climbed through - our first trip entailed multiple tests and a 4 day quarantine on arrival. Still more than worth it. Just about every location on the planet is in category 4 now with CDC - it is a recommendation not a ban.
