That was not what I asked. I read and am very aware of the requirements to get ON the ship and the requirements to re-enter the USA,,,,not the issue. I

If the cruise is only a three day cruise then getting of the ship at any port would not be an issue...but...I will go out on a limb here and assume the cruises will exceed the three day limit for testing....so on day four you get off in Aruba..no PCR test? On day five you get to Barbados...no PCR test? Day seven you return to SXM....no PCR test?

THAT was my question

Edit: this does not even consider the permission to enter form (EHAS or similar) that is needed for arrivals by air
