I visited Jeju-do for 2 days with my colleague about a month ago (12 - 13 Dec 2010). As this is our first trip to Jeju-do, I took the advice of tripadvisor forum and emailed Mr Won.
As I could not find much reviews on the hotels/pension house with ondol in Jeju-do, I also sought Mr Won's advice. Not only did Mr Won help us to check for ondols within our budget, he went a step further by making reservations on our behalf.
When we flew in to Jeju-do on 12 Dec morning, Mr Won first drove us to the pension house to check out the room. If we do not like the room, he was prepared to drive us to the other pension house to find one that is satisfactory! I was really very impressed with Mr Won's dedication.
After confirming the room, our tour starts. Along the way, Mr won explained a little about Jeju-do and was very knowledgeable about the sightseeing spots. Even though the weather was a bit wet, we managed to have a relaxed drive with one day on the east and west on the other. Mr Won is extremely patient, polite, understanding and made us feel comfortable throughout the 2 day trip. He did not set any time limit on any sightseeing spot. So we really enjoyed the trip at our own leisure pace. Even when we accidentally overspent our time at Sunrise Peak, Mr Won was very nice and very patient about it and adjusts the itinerary accordingly so that we can still cover our 2 day trip at a leisure pace.
Since we expressed interest in eating authentic Korean food, Mr Won brought us to the local shops for meals and ate with us. How do we know that its authentic local food? Cos we were the only foreigners in the shop and the rest of the patrons were local Koreans and their family. Furthermore there aren't any English menus. Mr Won would then translate the items on the menu and recommend the food items to us. I must say that the price was reasonable and the food was simply delicious!
In the evening, we went back to our room. The room was great even though the instructions for operating the heaters and underfloor heating were all in Korean. The room is like what you would see in a typical Korean drama where rooms are in a row and the doors open outward. There is a pantry in the room for family to cook their meals. From what Mr Won described, these are pension houses that local Koreans will go and stay instead of hotels. So we are getting a real deal and at a good price.
All in all, I would say that I had an enjoyable time in Jeju-do and its all thanks to Mr Won. Even though he only covers Jeju-do, he offered us assistance if we ever need help in Seoul. That's the kind of warm and helpful person Mr Won is! I will definitely recommend him to anyone looking for a free & easy schedule. He can take you to all the spots that you want to go without setting a time limit as to how long you take at each spot.
