Hi
CAlex,
To answer your question first: many of the people going in the next few weeks as part of a great BA sale that was on are staying at the IC Parnas, there are some that are staying at the Millennium as well but generally the preference is to stay at the IC or the new Conrad as you mentioned.
If you weren't aware of it...maybe check out this thread to see if anyone will be in Seoul at the same time in case you feel like meeting up with some fellow FT'ers...
