  1. Hi Grace,
    Book tickets to Seoul from mid Dec for 2 weeks. However, it seems that weather is expected to be very cold and wonder if you would be able to suggest any agenda for a family of 4 including 2 teenagers age 17 & 18. Any suggestion would be helpful.

  2. Hi Clara,
    Yes, it can be very cold in mid-December in Seoul, like 0℃ ~ -10℃ in the morning and night. The temperature in Jeju in December might be 0℃ ~ 10℃. Wherever you visit, you may need warm clothes and hot packs.
    How about going on a ski tour with your family? There are many great ski resorts in Pyeongchang, Gangwon-do. Please, take a look at the article, 14 Best Ski Resorts in Korea.
    Lotte World would be a good choice as half of the park is indoors.
    I hope it helps. Have a nice trip to Korea.
