last week due to the very scraped off conditions and hard hard snow(?) they waited until 11 for some groups to start. Everyone seemed happy enough at the end of the day. 20 in a group though for skiing. If you can afford it, I would highly recommend interski. They were brilliant and they have a max group size.
there is always snow to learn on, instead of learning at the bottom you will go up the mountain to learn, you will have a good week, don't worry about having to ski back down on your first day, the ski lift goes both ways
