The buses start running around 9:30 a.m., they leave as they fill up. When you get off your plane, you take a tram over to the main terminal. At the end of the hallway, you'll see the
DCL cruise reps waiting for you.... They will tell you what to do from there and direct you to the buses. One good thing is; you don't have to get your luggage from baggage claim, you just go to the bus and your luggage appears at your cabin later in the day.
Relax, sit about 1-2 seats back from a video/tv (that way you're not right under it, craning your neck) and enjoy, it takes about 45 minutes to get from MCO to PC (once you start driving).... one of the best things about the bus is seeing the Magic as you come over the hill right before PC, it's wicked cool!!!!
The bus drops you off right in front of the terminal , you go in the door, go through security, go up the escalator and get in line at check-in... it goes fast! Before you know it, you're boarding the ship!
