I notice this article didn't mention Grenada, but when I called AA they said the island open to tourists. We have a rescheduled cruise in November from Grenada thought St. Vincent and the Grenadines to St Lucia and back. I notice St. Lucia doesn't require a timely test is you arrive through the Caribbean "bubble", so I'm hoping this is the case when (more likely if) the cruise goes off for all the islands. I'd hate to have to take 5 tests during the cruise as we cross borders, especially if they charge $100 a pop. But, maybe the fee is worthwhile in order to escape the "nose torture" of the exam (I've had 2).
