It is correct that in the Orlando area,
Disney Cruise does not provide transportation from the airport to hotels. However, some Disney Cruises leave from ports other than Port Canaveral, and
DCL also offers booking services for hotels in the general areas of those ports or nearby airports.
Although I haven’t used it, it is feasible that DCL offers transportation from airports to hotels, particularly in Europe where many guests coming from the US arrive the day before the cruise.
