Yes, the Ecrins is the place to go for a group holiday. There are plenty of apartments to rent in Vallouise, hostel (gite) accommodation in Valouise or Ailefroide, or a campsite in Ailefroide. Oodles of VF, trad, and sport climbing within a short drive, as well as great walking, cycling, rafting, and should you be so inclined, alpine climbing. The scenery is superb and the climate very nice (I have spent two separate weeks there - in June/July - and not had any rain at all). It can be a bit awkward to get to by air in the summer - Turin is the best airport, but as far as I know there are only flights from London. Email me if you would like more information.
