when r u going to busan? m going there next month too..which part of busan? i live there..u can pm me if u need some help..

I came here to ask a few things before. Now my turn to contribute some infomation (although it'd been almost 6 months since i travelled to korea)

It was my first time travelling alone to a foreign land(malaysia plenty times lah).

Total spending of the whole trip include air ticket : +-RM5500
Total days : 15 days

Date : 5/12/2009 - 20/12/2009

Places visited :
Incheon(1 night) > Seoul (1 night) > Yongpyong (1 night) > Seoraksan (3 nights) > Chuncheon + namisland (1 night) > Seoul (7 nights)
Accomodation :
As I'm a student, I'm travelling on budget. My girlfriend is studying in seoul, and hence, she travels with me during that period of time. Travelling on budget means i couldn't afford to spend Rm300 on hotel room per night, looking at the period of days I'm planning to spend in korea. I stay in Motels. Motels could be find in every corner of korea. Its so easy that everytime i pop up my Garmin GPS and look for accomodation, i could find them within walking distance. Motels in korea is NORMALLY meant for young couples to seek some fun, and hence the design of rooms are catered for them. YEs, big mirrors, big TVs, nice bathtubs(higher class one). This might not be the case for tourist place like Seoraksan(I had a awesome motel there with kitchen, bath room, and big room). The comfort and cleaniness? Great. No problem with that even in cold winter they have.

Motels normally cost around 30000 - 60000 won. I normally get around 35000 to 45000 during my trip there. I got some really nice price in Seoraksan as it was low season, only 45000 won for big big rooms.

Transportation :
Bus(inter and intra city), Taxi(on some occasion), Subway(often in seoul).
Try to buy the card like touch n go. Its cheaper by 100won when you take bus. It is a must! You can get your credit in the card returned with the machine in most subway stations.
I have my Garmin GPS with me to look for accomodation and laptop to find recommended motels. It is important to me as i did not book any accomodation before hand.
Call their tourist help centre to check for intercity buses, stations and so on. OR ask the locals. Pick the younger people as they could understand english better than the older generations.

Food :
This sections plays a major role in my budget. It is expensive, but at the same time, i find them delicious. I could recall few good food i've tried is Chuncheon's Dakgalbi. If you're really on budget, you might be like me, finding myself most of the time in fastfood restaurant(Lotte(must try), Mcdonalds, KFC) for breakfast or lunch They do serve some nice burgers (better than malaysia's one, ecpecially their korean special beef burgers). The fastfood restaurants are cheaper compare to those tradisional korean food in tourist areas. I fall in love with their soju, i had them every night in the restaurant near my motel and grilling pork for supper(the cheapest grill pork i could find around). It's a MUST to try their grill pork and beef (even though some of them cost rm100+ per meal in a not-so-high-class restaurant).

Having a kitchen in your room is great, you could cook yourself breakfast with their not-so-cheap Instant noodles.

Oh ya, 7-up in Korea is different. I forgotten the name, but I'll add on later. But I normally just take free plain water as the prices for  drinks could easily kill my appetite.

I love the 10-story tall ice-cream!! You could find them in most commercial area like Myeongdong and nice 2 eat during winter! It doesn't melt XD Lots of flavours to choose from, a must try.

If you couldn't find cheap food in some area you're travelling on, worry not! Just pay a visit to FamilyMart(7-eleven alike or any convinient store), they sell some delicious Seoul FreshMilk and nice Kimbab!

Shopping :
I'm not a great shopper, but I do know some stuff that is cheaper than malaysia.
Facial products like stated, but many doesn't not know that camera bags, photographic accesories are very cheap in korea compare to malaysia, easily 50% cheaper. I got my KATA camera bag there. Not to forget, sanyo eneloop rechargeable batteries are 30-50% cheaper than malaysia, depends on ur bargaining skill. They could be easiliy found in Namdaemun.
Must do :
1) River cruisse in Hanyang river, korea
2) Watch korean stage performers (I watched JUMP and Nanta) They cost more than rm100 per person. I prefer Nanta, but it costed me Almost RM200 for VIP seat. But I never regret watching it, its very lively, a MUST TRY!
3) Namiseom island, cycling with ur loved one and take some nice pictures!
4) Try the 6 hours trail in Seoraksan. The scenery is breath taking (even though it's not yet covered in snow!) I will update this post to put in all the names. I forgotten.
5) Ski during winter! It's tiring, but fun! Make sure you have coach to teach you. It's fun, really.
6) Palaces. It's not the authentic one, but its good to know some history of korea. Most of the palaces in korea are rebuilt in the modern days, unlike china. I spent 2 days alone on their palaces, taking pictures and enjoying their history trails.
Last words,
Seoul's subway map isn't that hard to understand. It's fun to figure it out and very swiftly, you can wander around Seoul like I did. Did I mention I spend 7 days in Seoul? Subways fares, when accumulated, is'nt cheap at all!(cost me close to RM200)

If you have any problem, just ring their tourism help centre. They speak good english and very helpful.
