Where would you be if you are now in Korea? Do you want to visit and shop at Seoul? or maybe to learn about Korean history at say, Gyeongju? How about tasting authentic Korean food in Jeonju and then board a flight to Jeju Island the next morning for lunch?
After a tour around Jeju, why not fly back for dinner at Daegu - the birthplace of Samsung? You can actually do all that - hotels and round trip airline tickets to Korea fully covered by KTO (Korea Tourism Organization).
This is the link to participate. If you are lucky, you might just be among the lucky chaps to travel to Korea for free. Who doesn't like people paying for your flight ticket?
