Many people go to Korea because dramas and K-pop have captured the hearts of millions, so travelers want to see the filming locations of their favorite series and buy souvenirs.

Travel Planning & Tickets
First, make a plan for where you want to go and what to see, and find visa information. Now, to enter the country, you only need a K-ETA - an analogue of a visa, which can be easily issued on their official website: you need to attach documents and pay 10 thousand won.
Next, you should choose air tickets with or without a transfer - it all depends on which city you want to go to. If you arrive in Seoul at Incheon Airport, then you can also exchange currency and buy a SIM card there.
When choosing a hotel, think about how you will get to the places you want to visit. Of course, it is very convenient to live in the center and walk everywhere, but hotels there can naturally cost more.
What to see in Seoul?
First of all, you can go to Gyeongbokgung Palace, the main building of the Joseon Dynasty. Try to arrive early so you can see the changing of the guard at Gwanghwamun Gate at 10:00 AM and 2:00 PM. To visit the palace, you need to buy an entrance ticket, but if you rent a national Korean costume, then the entrance will be free. The second most important palace, Changdeokgung Palace, can also be accessed for free if you rent hanbok. It will especially appeal to those who love historical dramas.
Then you can go to the Buddhist temple of Chogye, the central building of Korean Zen Buddhism. Walk along the Seoullo 7017 overpass, which has now been turned into a park where flowers grow and art objects stand. Take a look inside the Seoul Tower, offering incredible views of the city from the upper floors.

On the next day of your stay in Korea, drive to Nami Island, home to two large parks, Petite France and the Garden of Morning Calm. You can get here by metro, ferry or bus. Here you can spend the whole day walking through the picturesque natural areas.
By the way, the drama "Winter Sonata" was filmed on the island - a memorial plaque and a statue with the main characters remind of this.
