The airport shuttle goes directly to the car rental store, which takes about five minutes. The shuttle driver was very friendly. Upon arrival at the car rental company, there were staff members to guide me, and they were very enthusiastic. There was a line for processing the paperwork, but it didn't take long. The service staff were surprised to see that I was returning the car in Chicago. I told them I was going to drive Route 66. I had booked a Nissan Quest but waited for a long time, so they ended up giving me a Dodge, which I was very happy with. It made me feel more secure for my long trip. The car was almost new, having only driven over 2,000 miles. The fuel tank capacity was also high, more than a Toyota Sienna. While a full tank on a Sienna shows around 300 miles, the Dodge can reach up to 500 miles, which is reassuring when driving long distances without frequent gas stations. Of course, there are plenty of gas stations on Route 66. For Highway 1, I would recommend a vehicle with a large fuel tank. After confirming the vehicle, take the slip, find your assigned parking space number, and then just drive off.
