While I would not bet MY vacation on it, my feeling is that the information on the official page is what is required, in order to not have to get re-tested on SXM. The tourism webpage shows what you can 'get away with' in order to get on island, get re-tested, and quarantine until the test results come back. GaryB posted his story here regarding not having the exact right test, getting on island, then clearing quarantine. I think that is what happened with Lesley's client also. So that is apparently what is happening, in reality.

As I said, I wouldn't bet MY vacation on that..
