I am sure that this question has been answered many times....but.... the guidelines seem to change.
My wife, son, and myself are fully vaccinated, specifically up to date. Both my wife and I have had 4 Pfizer vaccinations, and my son has received three.
We plan to do the antigen test. Our sailing date will be Sunday.
Can we do this test on Thursday, or do we have to wait until Friday.
Sorry if this question is redundant, but we want to avoid any problems at the terminal.
