Hi Linda,
I did the traditional anti-clockwise route in 9 days last year, doing 2 stages a day for 2 days the latter half of the route to fit it into 9 days. Was quite heavy going though as did it solo carrying all camping gear as started about 6th June before refuges open.
Would also have been nice to walk "light" and stayed in refuges, can heartily recommend the Col du Bonhomme refuge for friendly staff where I had lunch and the lovely Bonatti hut for sheer location.
If you fancy a day or two's rest in a fab campsite with amazing location in the Val Veni, Courmayeur, with great kitchen and BBQ facilities, small bar and shop and lovely friendly people try www.campinglasorgente.net
Got pics of tour at:

Feel free to mail if you have any more questions, enjoy it was fab experience!
Jon-Paul.
