Don't forget about the GoF scene at the Dursley's. Arthur, Ron, Fred,
and George all managed to get stuck in the Dursley's blocked-off
fireplace at once. It seems you must travel one at a time, but once
you're there, you'd better scooch out of the way quick! 

But, does this only apply to traveling by Floo powder, or to the
communicating-with-your-head variety as well? Don't know. I'll have to
run out to the Floo store and pinch a bit of powder to find out. Be
right back...
