Hi Kathline,
if you want to have cultutal experience,
visit Gyeongju or Andong. I think Gyeongju is the best.
you can enjoy Spicy Stir-fried Chicken(´ß°¥ºñ) in Chuncheon.
One day trip to Chuncheon is available from Seoul.
If you want to join the Mountain Trout Ice festival, come over here in January. but it's really cold~
If you have any questions about Chuncheon, feel free to ask my sister who writes English perfectly.
She is an Air b&b superhost in Chuncheon which runs "A relaxing home for guests"
you can also enjoy a lot of activities in Seoul.
after your plan's fixed, e-mail me.
