In reply to ianghogg:
Taking the extra equipment to camp will be a pain for you! It's definitely the norm for people to be walking the routes in approach shoes with a 30L pack on. They give some odd looks when you're there struggling with an exped pack on!
Camping is definitely an offical no. I was told that some huts will let you sleep on their floor or in their garden if you ask nicely for a smaller fee. The 2 huts I asked said I couldn't.
However, if no one sees you, then you have no problem.
If you become a member of the SOMETHING (somebody help me out), there are huts that give you discounts. The AAC gives you the same benefits.
Alternatively, you could plan routes than use un-manned bivy huts. These are usually quite high up and will make your days long though.
It's probably worth taking some snow security. On the trek there were steep snow patches that crampons would have given comforting security on. There was one VF route that had significant snow on which we didn't expect and although I was happy going down with stiff boots, my partner totally sketched out.
I flew from Gatwick to Milan and the same back again. Was a bit faffy with trains to the mountains but had a nice stop on the way back in Verona.
I hear most people will go from Venice or...over the border from Austria?
Get maps when you're out there - it's always easier. There is a german website that lets you explore the area online (similar to OSGetaMap) but don't have the link on this computer I'm afraid.
