George--Here is a link to testing at various places on the island. Link

Do you need a PCR test for sure, or will an antigen test work? If you're returning to the US, then an antigen test will be fine. They are cheaper and quicker. We have used Medwork in the past and will use them again soon. They give you an EXACT appointment time, and they run absolutely ON time. You can make an appointment online a week or so in advance. You have to pay in advance, but if your plans change, you can cancel and get your money back. If an antigen test will work, you can go get tested at your appointed time, and will be out of there by maybe 10 or 15 minutes total time. Then go eat breakfast or whatever, and by the time you finish breakfast, you can go back and pick up printed copy of your results, OR have them email them to your phone. Very easy, very organized. They do PCR testing also, but I have no idea what the turnaround time is on those tests.
