I'm planning a visit to Seoul in late Oct - early Nov and am thinking of staying at JW Marriott Seoul (I have loyalty reward points that I can use). But I'm not sure if it's inconvenient to get to Myeong-dong from the hotel. Would you be able to advise me - by subway, how long will it take?
Also, I'm planning to visit Lotte World and Everland. Is it accessible from JW Marriott? Or should I stay at Lotte World and Everland instead?
