The procedure in Orlando is to go down to level 1 and go through the exit doors across from the National counter. Go across the street to the garage (there are lots of signs pointing the way). Once in the garage, look for the mini-van aisle (sizes are on the pillars). All the cars have the keys on the seat or in the ignition. Pick the one you want and drive to the exit booth. At the exit booth, give the attendant your license, EC card, the car identification card from the dashboard and any special coupons or discount cards. Your credit card # is on your EC profile, so no need to show it. The attendant will process it and off you go! Very efficient! On the return, just follow the signs to rental car return and then to National's area. The attendant will come up to your car and use a hand-held machine to scan the ID # from the car side window, you don't have to show anything. They process the receipt and hand it to you. If you have checked luggage and your airline has curbside check-in, we always check the luggage first before returning the car so that we don't have to lug it from the car over to the terminal. Then just circle back around to the car return exit. I've used National many times and highly recommend it, especially Emerald Club.
