South Korea

Flight time from Osaka, Japan to Seoul, South Korea is 1.5 hours. Express train from Incheon Airport (ICN) to Seoul Station takes about 45 minutes. There is a non-express train that takes about 1 hour and costs less.

From Youtube video channel, Lais, entitled 3 Days in Seoul South Korea - A Travel Guide for First-Time Visitors.

Get a T-Money card at kiosk for metro and buses - 20k won (about $20) is good for 3 days.

Google maps works good for metro, bus and driving but not so good for walking. For walking download the NAVER Map app.

I did a cooking class at the Korean Cooking School.

I did a GYG walking tour in the Gwanjang Night Market in Seoul; the guide's name was Rocky.

MAJOR SITES
Gyeongbokgung Palace - the grandest of the royal palaces

For a good breakfast try Cheong su dang Bakery, 31-9 Donhwamun-ro 11na-gil, Jongno District (Closest subway stop is Jongno 3-ga on the number 1 line.)

ACCOMMODATIONS
Hotel Skypark Myeongdong 3, 139, Toegye-Ro, Jung-Gu, Seoul - a very popular and highly rated 3-star hotel.

I stayed at Fraser Place Namdaemun Seoul, 58, Sejong-Darron, Jung-gu, 04526 - a fantastic place! I had the deluxe double room which had a separate living room and bedroom with a king size bed. Closest subway stop is City Hall on the 1 line which is about a five minute walk to the hotel. The City Hall stop is only one stop north of Seoul Station.
