We plan to spend a wk in South Korea, will fly from HK to Incheon airport, arriving at late night. We want to rent a car the next morning. We have 5 adults, want a 7 seat vehicle. I have looked the car rental companies in the Incheon airport : avis and Hertz. Apparently no 7 seat vehicle is available. Any advice as to how to find such a car to rent around Incheon airport?
