Just landed in St Maarten from the USA .. We had our Negative Covid test in hand(antibody test). But they made us pay $125 a piece to take another one at their airport. It have to be an PCR test.
Which is odd because no one gets a PCR Covid test back under the 72 hours as they required. So they are definitely making a big buck of the USA.

Long story short! We made it in and we are ready to enjoy our Villa
