I’m off hopefully to St Lucia on the 12th Sept. You have to have test (up to 7 days) before arrival and submit pre-departure form and test results to St Lucia government. You also have to stop in a Covid approved hotel (Sandals in my case). There have been no new cases in the last two weeks and only 26 since the start. Travelling in F so I will post a short synopsis of experience once I arrive.
