If you are going out of Port Canaveral try CRUISE PARKING OF PORT CANAVERAL. I know they are on Face Book and you can register on line..don't know their web page
They have an air conditioned waiting lounge, a bakery and a room for kids. THE BEST..they are cheap, load and un load your luggage, park your car and take you to and from the ship. We haven't tried the Park & Cruise but I hear they have new owners and are not waht they use to be.
