In reply to Dave:
The Haut Cime in the DentDu Midi is great. All others in the group are Ad or above
The refuge Dents du Midi is unmanned but I would highly recommend a night there. A stunning place and once you get the fire going really cosy as well. You can access the Haut Cime by dropping down to the col. You won't regret it.
