I decided to rent a car from Alamo at MCO (picking up and dropping off there). I signed up for the Insiders program, gave them all my info and did the online check-in to skip the counter and go directly to the garage. I did not prepay, though...I chose to pay at the airport. I was just wondering...when do I actually pay them? Do I do it when I pick up the car or drop it off? I've never rented from Alamo and it's been so long since I rented a car. Has anyone done it this way? For some reason, I'm paranoid that I'll get off the plane, get to the garage, and be sent back to the counter to wait in a long line and pay. I know it's a dumb question, but I just want to be sure.
