I've read that the best periods to visit Korea are autumn or spring. If someone's eager to spend a month in Seoul (+ road trips across the land to visit beautiful landscapes etc) how much money will it cost? Any information concerning where one could stay (hotel or anything else) that wouldn't cost that much so as most of the money would go on road trips, food and soju is always welcome. Any bonus information concerning anything you consider important would be more than welcome. Thanks a lot for your precious time in advance.
