I've already send the mail. I'm comming. As for how I come, dunno, maybe by train (although very expensive), maybe by car (but I need a GPS then cause I'm hopeless
)...
Staying overnight? dunno, it is possible to go back the same day by train (to Belgium/Netherlands) if the meeting isn't till the night though. For others, there are many cheap hotels in Paris also, (youthhostels), maybe I'll do that too, dunno yet.
But, when I can drive (I hope so, although the car wouldn't be mine, so let's hope) I can bring 4 other people from Belgium/Netherlands....
All depends when we have more info (like location/time).
