Hi! Right away on you questions.
Last years InterNosCon had between 70 and 90 attendants each year, and we (the indie community) are always to invite people who are not part of the Italian indie scene, both coming from abroad and Italians who don't usually play these games.
I must probably clarify that INC is not a fair: though the people who publish games probably will have some copies with them if someone needed them, the main focus of the convention are gaming slots and guests panels; it's a two-three day marathon of playing, laughing, eating tasty food and drinking great beer.
French authors (well, everyone, acutally) can come to InterNosCon as fellow players (like, for example, Frederick Jensen --
Montsegur 1244 -- to the 2010 edition), but I think that it could be arranged a panel, maybe about publishing in France or about the French indie scene, or about the games they wrote (that would be interesting!). I'm not one of the organizer, though, but I can ask them; anyway, there's a dedicated board on the GenteCheGioca fourm, here:
http://www.gentechegioca.it/smf/index.p ... 122.0.html -- it's in Italian, but you can write in English, that's fine -- where you can find some information and ask directly to the organizers.
As for the accomodations, usually players book a hotel room nearby, and this year there's an agreement with some hotels, so that the cost of the convention plus the room is really convenient. All the fees and hotels are displayed on the website, here (

http://2012.internoscon.it/en/partecipa/pernottare/ - that is actually not up-to-date as the Italian section:

If you need furter informtaions about accomodations, I'll call one of the organizars to step in this discussion.
