Wondering if you will get enough use out of your tent to make it worth lugging the thing half way around the world?
If you are even a slight outdoor enthusiast, I would encourage you to do so. Camping in Korea is one of the best ways to see the many beautiful national and provincial parks scattered throughout the country. Many of these parks offer campgrounds with full utilities for as little as 3,000 won per night.
Camping in the parks can help you get an early start on those longer hikes, or simply provide a scenic place to relax with friends after a long work week. If you don't have a tent, or can't find the space to bring one, most of the parks also offer heated shelters where you can spend the night and even rent a blanket.
For those who are more into relaxing in the sun than hiking, Korea's many beaches can also serve as a good place to sleep and often have bathroom facilities on site.
