We have some friends who had plans to arrive on Jan. 3rd. from the US. They have a 5 day covid test scheduled but are unable to re-schedule to a 3 day test as the reservations for that are backed up and unavailable. Phone calls to Dept. of Tourism confirmed the 3 day limit. Seems that they are stuck and out of luck. I assume that many people have found themselves in the same situation. Anyone know of a solution to their problem?
