In reply to kingjam:
The woods?
Guess you might be after something a bit more luxurious than that though!
We just discreetly camped for our whole trip. The only place we struggled to find a spot for a tent was below the Fiames Arete - the slopes were steep and the only place to pitch a tent was directly on the footpath - with rocks instead of pegs!
But I can thoroughly recommend wild camping when possible - you don't get woken up by drunk folk coming back from the pub, you get into the habit of getting up at the crack of dawn, you can normally make sure you are very close to the route, and you save a lot of money.
Getting on the routes early was really beneficial on our trip as we always avoided the afternoon thunderstorms and crowds on the routes.
Not for everyone though, and you have to be discrete...
