I did some searches, but didn't really come up with too many prices.

I will have a forced overnight at ICN. I really don't want to trek into Seoul and would rather just hang around ICN or somewhere close to ICN. I hear it can be a ghost town so I would like somewhere relatively close <15 min away but still a neighboorhood where I can wander and explore and eat.

Suggestions?

Also I didn't know about expected hotel prices or with whom I could book in advance.

Thanks beforehand for some quick advice. I'm leaving in a couple of days.
