Then we ended up walking to the main terminal to catch the train instead of waiting for the shuttle. There were very few signs in English and it took us a while to figure out which train went where and whether to take monorail or not. Ended up taking the the train to Shinagawa, then Yamanote towards Shibuya. Was probably an hour faster over all, but for the first time it seemed like a bit of a hassle.
Yes, it matters where you are going in Seoul. My office is in Yeouido, which is about 20 minutes from GMP, so that's a winner. There are lounges both in GMP and HND, they are perfectly fine, probably comparable to most lounges in NRT. Walking from the international terminal to Terminal 1 or 2 to take the train is a real hike. That's one hassle I wouldn't really deal with. What I usually do is walk out and get straight on a cab at the international terminal. I'm in my office in Ginza in 20-25 minutes.
