Lotte Rent-a-Car Jeju is a car rental service on Jeju. You can book online and, after arriving, confirm with a QR code to receive your car without going through the counter. It is five minutes from the airport, and you take a shuttle bus to the office, where electronic check-in shortens the time to vehicle handover. An international driver's license alone is not enough; a foreign driver's license and a passport are required.
