I keep reading that it's either a 72 hour or a 3 day PCR test prior to arrival in Barbados from uk..and their is a difference! On the UK GOV web site it says ...
"For example if I arrive in Barbados at 10pm on a Saturday I can have the pre departure test on the previous Wednesday at 10AM..This means the test will be 84 HOURS old upon arrival but is that acceptable .?,.many thanks. Getting the test done and awaiting results is stressful enough without this confusion!
