Keep in mind that the 72 hour clock starts running AT THE TIME OF THE TEST, not at the time you receive your results. If you know that a RT-PCR is accepted, and that there could be a problem with a PCR test (no matter how small a percentage of people refused entry) Why would you roll the dice on any other test than RT-PCR ??? You have jumped through so many hoops to get to this point, it seems negligent to take a chance on throwing away all your hard work. Just my thought, good luck.
