Has anyone recently used National car rental in Port Canaveral? I understand they do not have a free shuttle back to the port, but how far away are they & how much of a hassle is it? When I try to book online, the only option I can seem to find is at the Melbourne airport. Is that correct? I know othe companies are more convenient, but DH uses Nat'l for work all the time, so that's why we would like to use them& take advantage of the points we've built up. Thanks for any insight you may have!
