I wanted to contradict the negative comments posted below about Flaine:
We have just returned from a first-ever skiing holiday with other more experienced members of our family. We loved it and will go back as soon as we have the cash.
We were all fairly nervous and booked into ESF (grande massif) classes every morning for a week. My kids (12 and 8) loved their instructor and their only complaints related to the behaviour of one or two (English) children in the class. I saw kids crying but mostly they were with their parents who were pressuring them to do too much too young, or responding unsympathetically to their inevitable falls and problems. My wife and I had an excellent instructor who got us from complete novices to happily linking turns in parallel within a week!
Generally Flaine seems to offer a no-nonsense family friendly resort for people who want to ski and relax without getting plastered. Only the most black-run obsessed member of my extended family was not able to get all the skiing she wanted.
Also very beautiful ...
