Do 'proper' French exchanges happen any more? You know, the type where you get shipped off to France all alone for a couple of weeks (I did three, my parents said 2 wasn't enough) to live with a French family, then they come back to you for a similar length of time?
I specifically mean NOT ones organised as a school party, with the whole (English) class getting together for lots of sightseeing / events - I mean the hardcore 'got to speak French all the time' ones?
