We have never had trouble parking at the cruise terminal in Port Canaveral. It costs around $10-15 a day. Of course, we always drive there (no car rental), so I’m not sure if we’d do the same if we had to rent a car…
I’ve heard that you can get free parking at the Radisson for the week if you stay there one night. There were some people on my last cruise that did that. They weren’t too pleased with the Radisson, though.
Are you going to WDW first? You can book a shuttle through Mears which will take you from Disney Resorts or Orlando International Airport. I’m not sure how much it costs, but I’m thinking it wasn’t cheap… maybe around $75. I’ve never done it, but I know others who have.
Also, Welcome to MB! :happy:
