Hi Carrie, welcome aboard! I bet you are really looking forward to your cruise with Mickey and friends this fall!
It's easy to park at Port Canaveral when you arrive for your cruise. You can park right at the terminal and you have two different pricing options, regular or preferred parking, both of which you can read about on
Disney Cruise Line's Departure Port webpage. Currently, prices start at $60 for a 3-night cruise, up to $120 for a 7-night sailing.
Another option that is popular with Disney Cruise Line guests, and will save you some money, is to use Port Canaveral Park n' Cruise. Look it up online, and you'll find the details there. It's located about five minutes away from the port, but they offer a free shuttle service taking you between the parking lot and the cruise terminal.
Check out both and see what looks best for your family and your budget. Either way, you'll be at the port and ready to board your very magical cruise with Disney, knowing your car will be waiting nearby when you return.
Happy planning, Carrie!
