You can park your car at MCO. They are charging $17.00 a day. It will be cheaper if you use one of the Park and Pay near MCO. They offer shutter to MCO. If you check Alamo online, you dont have to go to the Alamo counter. Just go to the car rental garage and pick your car.
You do pick up the car at the arrival terminal, no need to any shuttle service. Not sure where to leave your own car. I am sure they have long term parking in MCO.
