I am not sure if I am comming yet, but come October, I'll know. I'll probably be doing it via couchsurfing or somesuch. Almost 300 euro for three days is a bit steep for me. I'd rather spend those money on more adventurous pursuits, as usual. :-)
I'll let you know when I know for sure, so you wouldn't have to lug a book around for no reason, in case I can't go.
