Questions about South Korea.....

Have a flight layover for a day and hotel is in Incheon, is it easy for a non Korean speaking person to get to Seoul on the subway? I have heard there is English signage as well as Korean in the subway?
Thanx

It's kinda far.... Yup, there's English on the signs. Very easy to understand. But I'd probably take a taxi, because it might be confusing/stressful if you've never been there before. But however you decide to get to the city, just have your station written in Korean letters and show somebody. Koreans are soooo nice.
