Jersey City hotels (across the Hudson river from NYC) are slightly cheaper but still pretty expensive. There are a couple of hotels in my town which are next to buses that'll take you into the city in 15 minutes. Don't know how expensive those hotels are though. I'll check if you guys are interested.
Could you please let us know which hotels these are and where these buses drop you off? I'm planning on checking out the NYAF on Saturday for Rika, too. There's quite a distance between the convention center and Randalls Island Park. :\ Recommendations? Pick a hotel somewhere in between those places? Somewhere on Manhattan Island? Somewhere in Queens? Jersey?
Edit:
Saw limit's post. Ah, right I remember reading something about Sungyeon's back? Ack, KARA's the main reason for me wanting to go to the Chuseok Festival! Well, I hope the KARA camp keeps us informed on her progress.
