TripSem is a set of calculators for people visiting Korea. Each one takes a question that comes up on the trip — how to get from Incheon Airport to your hotel, which transit card to buy for Seoul, how much mobile data you need, whether to rent a car in Jeju — and works it out for your group, your days and your plans.
The fares come from the pages that publish them: AREX and the Incheon Airport bus search, Seoul city, Jeju Province, the three mobile carriers and LOTTE rent-a-car. Every calculator lists those pages with the date they were checked. Where nobody publishes a number — limousine bus travel times in daytime traffic, for one — the result is marked as an estimate.
Two examples from the current data: four adults landing at Incheon Terminal 1 and heading to Myeongdong pay ₩68,000 on the limousine bus, or about ₩54,100–₩57,100 for one taxi with the expressway toll. In Jeju, three days of sightseeing from Jeju City come to ₩26,850 per person in bus fares, against about 6 hours at the wheel by car — and the bus rides take 9 to 17 hours.
