NOT in terminal
Pros: Counter staff were very friendly and courteous.
Cons: When I booked this reservation, I was mislead into thinking that Payless was located in the terminal at Chicago Midway. Not only was it not in the terminal, it wasn't even located in the rental car building where all the other agency are. I had to take the shuttle from the terminal to the car rental facility. Then I had to wait for a Payless bus to pick me up and take me to the Payless facility, located in a residential area a few miles away. If I had known this at the time I booked my car, it probably would not have been that big of a deal. However, since my reservation stated pickup was located "In Terminal", this experience was quite aggravating.
