Mmmm. If it's on a Friday -> Saturday, I suppose I can put you guys up for the night at my place. When Bell's here, we usually pull all-nighters at IF (hence his sleeping on the DDR pad), but for multiple guests that's probably a bit much.
Personally, I'm a fan of those Japanese 24-hr netcafes. 5 bucks for 2 hours and your own private booth with headphones! That, and in Japan, one always, always has tissues handy (cute girls handing packets of them out advertising their pachinko parlors). Eheheheheh.
