Is there a fee to leave your car at the Port? I was surprised to get a really cheap car rental through Priceline, and as it works out it was close to the same to get the car, park it while on the 7 day, then return it to the airport (other option was rent car for use in Orlando for 3 days, then return in Canaveral, then re-rent in Canaveral for last day in Orlando, and return to airport). With four small kids, and car seats to install and uninstall it was worth the few extra dollars. Anyway, I'm wondering if I erred in my calculations because I forgot to consider parking fees at the port?
