Sorry, it's on the Tourism Bureau page. Link

It says "Incorrect type of tests are subject to retesting on site at the airport (US $125). " Since there have been something like 700 people tested at the airport, it appears they are following what it says on the Tourism Bureau page, not what the "official" page says. It would be REALLY nice if they would make consistent statements and keep to them. I ASSUME, without knowing, that a test taken too early qualifies as an "incorrect type of test".
