Hiwe did half last year and will be doing the other half this year. PM me if you like for more info.
We went: Trient- Trelechamp-les Houches-les Contamines-Col de la Croix du Bonhomme-Rif Elizabetha-Courmayeur.
Stayed in Gites and huts and a B&B.
About €40pppn with adjustments re kids ages. i.e younger kids much cheaper.
Our kids were 15, 13, 8. They had a great time based on their behaviour, number of photos, general skipping. They said however that it was torture.
Went quite light weight- two 32L rucksacks, one 10L ruck sack, ultravest and a kids sack.
There is a great Youtube video of a NZ family doing it.
