Pete Emailed me the details below on 2 places he's stayed,we will be staying in the same area,I plan to do a bit of research on accommodation to bring to the meeting, If anyone else finds anything of interest bring it along!

the campsite is Camping Les Ecrins, i found it on Google Maps, you can see how close the slalom site is, + contact details:

Distance 800mils and about 13hrs, but no stops! - think this would be about £220 in fuel (this not including all driving around during the week), need to add Toll Fees (Toll fee for Italy was £230, so will be less than this).
I will get river guides during this week, and if we want to arrange a meeting in a pub to discuss some more.
