check out some of the town car/limo companys like happylimo.com and fltours.com they have roundtrip rates per car for cheaper usually than it ends up costing with the shuttle and you don't have to worry about driving like if you rented a car. I think a town car that holds 4 people costs about $200 roundtrip from orlando to port canaveral and back to airport. Check out the transportation message board for more info!
