I understand Disney can do Airport to port transportation on embarkment day, but if we decide to fly into Rome a day earlier, does that mean we will have to arrange for our own transportation to the port? We will definitely be using Disney ground transportation going back to the airport, but not sure what to do on the first day, from what I've heard the ground transportation is always booked as round trip so we can't just book it for the return trip. Can someone has experienced this in Rome please shed some light? Thanks!
