I'd always used Lotte Car Rental before, but it's gotten increasingly expensive, so this was my first time renting a car through Ctrip. This rental company was very convenient; a dedicated shuttle from the airport takes only seven or eight minutes to reach the store, and there are staff specifically for foreigners. Because I speak Korean, the process was very quick; registration and handover were completed in about ten minutes, and I was ready to go. The staff also informed me in advance where I needed to refuel, the insurance amount, and assured me there were no problems with the car. On the last day, when I went to return the car, I forgot to bring my credit card to get my deposit back, and a staff member came to the shuttle bus to call me back—I was so grateful!
