Bus from Korea airport to hotel

You said: there is a bus at the airport that will take us to the hotel. It may be a hotel bus. If you want to get off the plane, you must go to the hotel at once. You can't go back to the airport late at night and take a bus to the hotel. Do you understand, it will take about 18:45 to leave the airport, and there is not much time at night. I suggest you make the following arrangements to save time. When you get off the plane, you can take the hotel bus immediately. Call a friend in the hotel room and ask him to pick you up at once. * * * Travel to Seoul. {Don't bother to buy a phone card, it's expensive and inexhaustible, and it's cheap and convenient to make local calls in the hotel room}. Friends can take you back to the hotel when they are finished in Seoul.

Don't wait for your friend at the airport. If you don't have enough time, you have to travel to and from the city, hotels and airports. If you need to take a taxi too late, it won't be cost-effective.
