Don’t use dollar at Dulles

Average, the car was a bit dirty.

Convenient for returning the car in different locations, with reasonable and fair pricing.

Take the shuttle bus directly to the car rental company.

Not bad. I initially thought there would be a Chinese translator at the counter, but there wasn't.

There were no preferred vehicles at the lot, only group vehicles. I almost couldn't rent the car because Bank of China credit cards do not support $0 purchase test. Fortunately, the emergency support from the rental company suggested that I make a small purchase. I bought a tank of gas, and the payment test succeeded. Although the Korean clerk was not very friendly, he let me try three times. Huge thanks to the emergency support team.
