We sailed out of FLL on a day when 6 ships were sailing also. Arrived at the port at noon and were on board by 12:30 - 12:45. There was plenty of parking in the port garage and hardly any congestion. Most disembarking passengers are long gone by 9:30 - 10:00 in the morning. You should have no problems getting there earlier rather than later. You also will have time to relax prior to sail away!
