We have been using Dollar Express for years. You fill out the driver information in advance and when you arrive at MCO you can go straight to the garage. There is a booth there and I'm pretty sure that on your first time using them you may have to give your physical credit card. Next time you go back there is a board where your name is listed along with where your car is located. Not certain that this is still their procedure but it was when we began using them years ago.
