i've never been, but a white friend of mine dates a s korean, he went to seoul, and loved it. i've heard good things about seoul in general. can't imagine the airbase is much fun though. just go. from my experiance with S. Koreans, they're a pretty friendly bunch. i'm studying with a couple skorean girls right now, and they;re both fine as a mofo. if you are the kind of person who likes to travel and see new things, it will be difficult to have a bad time.
