There are of course. It depends on individuals liking and preference. like historical places, theme park, shopping center, musuem, downtown, performance, club, mountain. So which suits your liking more? I guess you would probably check out at least three or four of them.

Korea is a modern country yet it still remains fiercely traditional. You can visit palaces like Gyeongbukgung, Suwon Hwaseong Fortress, Changdeokgung etc. Personally, I have only been to Gyeongbukgung, you can watch the guards changing ceremony. There is also a musuem beside. Check out the Namdaemun gate and Dongdaemun gate if you like photo shooting.

Theme park I would suggest Lotte World and Everland. Lotte world has indoor and outdoor parks, it also has ice skating rink, more or less like the one in pyramid. Just bigger in term of size. Everland consists of 5 themes. The t-express roller coaster is located at european adventure. You can find out more yourself.

As for shopping, it depends on what type of goods you are looking for. It can be very expensive or very affordable when shopping in Korea. Try Coex, Migliore, Lotte Department Store and Shinsaegae for high-end goods. If you are looking for unique clothing designs and accessories by designers, check out Cheongdam and Apgujeong street. Also, I would recommend Myeongdong if you like to shop with the crowd, you can find relatively affordable and expensive goods there. Of course, for a good deal, head to Dongdaemun and Namdaemun market. Dongdaemun is famous for wholesale, I heard from a Korean friend, she said all the goods sold in Korea, whether online or retail, all comes from Dongdaemun. However, go there at the right time. It is more expensive in the afternoon but cheaper at night, midnight. It's 24hours open anyways. Try underground shopping, you can find it in most places, Gangnam for example.

Go to Insadong and Samziegil if you have never been there. The things sold there aren't that cheap either, as it targets foreigners. Itaewon is famous for clubs, most of the foreigners and English speaking Koreans socialise there. For ladies, maybe you want to check out Ahyeon-dong wedding street. Hongik, Ehwa women university street and Yonsei street also popular among youngsters.

If you like parks, go to Namsan Park. Namsan tower and 63 City at Yeuido offer nice view too. Hangang river is a popular spot, you can cycle or rollerbalde, rental service is available. At night, you can take a walk at Cheonggyecheon stream.

Food wise, try out as many local delicacies as possible. Good exposure for your taste bud. Like it or not. Ha.

I have only been to Korea once in July, summer there is still cooler than KL somehow. Perhaps it's more windy there. Winter, no idea. Plan to go there in Jan again to ski. See first.

I would encourage all to visit Jeju and Busan city. Busan is famous with Haeundae beach. Many seagulls. As for Jeju, preferably not to visit in winter.

All said. If you have any inquiries about how to get there and its location, find out yourself. Try the official site of Korea Tourism Organisation. Go google. GOodbye.

No. I dont think I'd totally agree with your statement. In fact, it can be quite fun to travel alone at times. You never know what opportunity may arises from it. One can opt to stay at backpackers hostel and this increases one's chance to meet many like-minded travellers from all over the world. I would suggest Banana Backpackers or Seoul Backpackers. The price is relatively affordable compared to hotels, the staffs there are very friendly and helpful, and so are the travellers there. In fact, I travelled all by myself to Seoul for once. I was so excited about it and I got to meet many people and made many new friends as well, a wonderful memory I would never forget. ( :

Of course, it would be better if one has some friends there to guide one through. If not, get a volunteer guide. There are plenty and you can find them online.

So go and explore the world. There is so much fun awaiting for you !
