Left everything to the last minute. Am flying out Saturday morning, and arriving Saturday night there at 7.30pm

Questions:

Anything to see do on the first night given that I'll be there around 10-11pm in the city.

What is a good itinerary the next day - I fly out 7.30pm - so ideally should be at GMP Airport by 5pm. So far I have:

- Gyeongbokgung Palace and Changdeokgung Palace (I heard there is a garden tour here)
- Tosokchon Samgyetang for the chicken soup
- Bukchon Hanok Village

Could I add 1-2 other places?

I also end my trip via Seoul, arriving night and flying out 5pm next day - so ideally would like to spend the day shopping - although I probably could fit in a morning trip somewhere too. Whats is the shopping paradise/department store area in Seoul that's good for shopping.

Any helpful travel tips for Seoul would be appreciated also
