Thanks for sharing... Flying off this coming Thursday...
Be prepared for the cold... really chilling wind... I can survive Hokkaido ski resorts in mid-late December without gloves and ear muffs... but in Seoul I needed all those and a face mask as well... the wind into your face is really spine chilling... and do prepared some heat packs just in case... my bro brought some portable usb heater... very handy... put in pocket to warm your hands...
