I've got a long layover later this year in Incheon. flight lands at 5 pm and doesn't depart till 1:45 the following day. Is Seoul worth visiting at night? I'm not interested in clubs/bars/drinking. Anything else you guys recommend? What about hotel? Should I book a hotel in Seoul or close to the airport? I looked into booking a room at airport hotel (inside the aiport) but they don't have rooms.
