How much is a ferry from Incheon, South Korea to Dalian, China?

Question

I'm gonna be in Korea starting at the end of November, and for Christmas time, I think it'd be cool to go with my cousin(s) to China and hang out (they are in Seoul at the moment).

I'm not sure how much the ferry would be, and I'm trying to organize my trip as well as possible so I can see a lot of s**t in a short period of time.

Any idea?
