Update:
Arrived today. Entry is still a bit convoluted but they’re working out the creases. A full nasal lobotomy, lots of documentation and an hour later we were able to leave EIS.
Even though you’ve received your BVI Gateway auth. Be sure to bring your RT-PCR results, you’ll be asked for them a few times.
For those who are vax’d but paid the $175 entry fee online, they will either refund your $70 upon arrival or you can use it for the exit test. I emailed the Covid response team before we left the US and already have our exit test scheduled.

The scoop on the tracker band= they really are paper concert bands, the tracker itself is provided very nonchalantly in a small wet bag. We were told to just keep it aboard and plugged in...

Now for the good news, they told us to just return the tracker itself to the airport when we head home. No need to make an extra trip to the police station!!
Moorings base camp- 4-5 Q boats on our dock with lots of empty slips. All in all, boatloads of Very content travelers.
