Pat ; testing should not be an issue as all you need is a copy of the PCR test and your online form sent in and print out of the acceptance email St Maarten will send you. The system they are using now on arrival is extremely smooth and very easy. They do check all the documents but that is not an issue. The whole process from walking off the plane and immigration and getting our checked bags took less than 15 minutes, The Island welcomes you and are very appreciative that you will come and support their struggling economy.
PS the beaches are great this now and NO cruise people here on the beaches as well.
