In reply to barkell:
Back in 2010 I did this as my first trip to the alps too. We had good weather and spent one day near the Petit Aguille Vert looking at movement techniques and scrambling, one day walking up to a hut with an afternoon on crevasse rescue, and the final day on a small peak near the Chardonnet before heading back down.
Definitely stay in the campsite mentioned above as that's where you'll be meeting the guides and other course members. Chances are they will all be staying there too and it will give you a chance to be social in the evenings.
Remember that the Alps can be hot in the summer. Make sure you pack lots of versatile layers when you head out to France so that you can take the right thing on the day. I remember one guy in our group being really over dressed and suffering somewhat.
Make sure your boots are a good fit, are broken in, and fit your crampons well.
Don't leave your gloves in the hut if you stay in one (oops!).
If you can spend a few more days in Cham after the course to consolidate your skills you'll find it massively helpful. I wish I had done this, as many people in our group were sticking around and it would have been easy to team up and actually climb some proper mountains.
