Hmmm, I do see that. Sorry for my "correction"! I could swear it was three days previously, but may be confusing it when we had to return test and were transiting through PR.
On our December visit, there was a return test required for transiting USVI.
For February, we booked through San Juan to avoid that test, only to have the US add their own test requirement.
Hopefully our next trip will be less complicated!
