On the last day of the cruise, the ship docks around 7:00 am at PortMiami. The ship must clear customs before they will allow disembarkation to begin, and sometimes there are unforeseen delays.
We recommend that you do NOT book any flights out of Miami International Airport (MIA) that depart before 12 (noon) to allow ample time to get off the ship, navigate you and your luggage through customs, make your way to the airport and then go through their security rigmarole.
