First of all, it is highly recommended. The driver arrived on time to pick you up. Maybe because of the early morning time, the journey is only less than 1 hour, which is very good. When booking the ticket, it was like the flight back at 12 o'clock, but then the travel agency notified the airline to change the time and changed the flight back at 6 o'clock in the morning. The airport bus had to go to Seoul Station in the early morning, and the bus was in the early morning. It’s easy to comb, and you have to go back and forth when you go. Originally, it was convenient to get on the bus in Myeongdong, but when the ticket time was changed, the hotel had to add one more night and the book car, which was an extra cost. Fortunately, At that time, I did not know how much money I would like to make a tight booking, so I would get a 10% discount on the book car and even the day tour. Happy.
