Disney provides a transfer service from various WDW resorts to the port as well as from the airport to the port. According to my information:
The
DCL motor coach runs from/to:
Orlando International Airport to Port Canaveral
Port Canaveral to Orlando International Airport
Walt Disney World Resort To Port Canaveral
Port Canaveral to Walt Disney World Resort
The Walt Disney World Resort locations include the following hotels only:
Disney's Grand Floridian Resort & Spa
Walt Disney World Swan & Dolphin
Disney's Board Walk Inn & Villas
Disney's Contemporary Resort
Disney's Polynesian Resort.
Disney's Port Orleans Riverside (Dixie Landings Resort)
Disney's Port Orleans Resort.
Disney's Beach Club Resort.
Disneys Caribbean Beach Resort.
Depending on whether it is a one way, two way, or a tri leg trip (airport to resort, resort to port, port to airport) the cost will vary. I am not sure what a round trip is currently but I think it is around $46 per person. You may get the transfers from DCL. To buy them, you order them with your package, buy them from the DCL agent at the Orlando airport or at one of the hotels included in the packages. Hope that answers the question.
