The directions at O'Hare Airport are very clear. Taking the Blue Line train gets you there quickly. Once you get off, there's a whole row of rental counters downstairs. The process is simple, and you can head straight to the second floor to pick up the car.

Efficient and very convenient.

This Chicago location is run jointly with Avis. Firstly, there are no clear signs indicating that members should go to the second floor while non-members stay on the first floor, so I wasted an hour in line. The funniest part is that I then waited another hour and a half on the first floor because all the cars were rented out and they were waiting for returns. I landed at 2 PM and didn't get the car until almost 5 PM.

There were over twenty people in line, and only one person was working. I don't know what the others were doing in the office, but at the very least, they need to ensure the counter service. The service attitude was okay, but the unexplained charges were very confusing. I was charged a deposit twice, paid the rental fee in advance, and was unexpectedly charged again when returning the car. They said the deposit and charges would be refunded within two business days, but there has been no news. Make sure to purchase third-party liability insurance before booking, otherwise, you won't be able to pick up the car.

Maybe because it was a holiday, but I waited in line for half an hour.
