I'm a frugal adventurous traveller thus going on travel with me means taking public transportation, a lot of exploration by foot and constant interaction with local residence. This I would warn my co-travellers before going on a trip, besides group tours doesn't give you the full travel experience.

The transportation system in Korea is easy, convenient and most of all cheap. But you must plan your route carefully as you should consider travel timing and distance between sites to visit. However, language could be barrier as few Koreans could speak English. A basic Hangeul lessons and body language would be helpful. Although you might not probably remember your Hangeul lessons, you can try to interpret what they are saying...hehe :p You can visit Talk To Me In Korean for some lessons, it really helped me a lot :) Also, write down the places in Korean in case you might need help with directions. Koreans are very friendly and helpful people, they will go to the extent of bringing you to the place you are looking for.
