I'm assuming you mean Alamo's service? I can't answer your question, just wanted to make sure that's what you were asking, so other's could give you your answer. Ooops, looks like you beat me to the punch!!!!
LOL yeah
i know you go out the parking garage and i thought someone said theres a booth there you check in and then take a car, but I am not sure and nothing is coming up in the search I did.
Yes, you go over to the parking garage, I believe Alamo and national on floor 2. you go to floor two and you will see a booth with Alamo and National sign. go in there and they will take care of you. Very easy.
