I know if you miss the ship mid cruise you can arrrange to meet it at the next port. But what happens if the port is the last one before heading home ? Assuming you manage to fly home ahead of the ship, will customs allow you to board to retrieve your belongings, or will the staff pack up your room and bring your luggage out to the curb ?
I’m guessing the latter. I cant imagine customs permitting anyone to board, when they are trying to get everyone else off.
