A great little resort!
We spent a family Christmas there in 2003. We found the people very helpful and friendly and the skiing excellant. Perhaps a little limited for beginners but a great deal of lovely cruising for intermediates and enough of a challenge for folk looking to improve. The capacity was excellant and even when the Italian holidays started there were never delays on the tows. We stayed in the Crystal Chalet Hotel which was very good value and great fun.
We never did make it to France but the trips to Sestiere and Sans Doux were very good.
The younger folk in the party enjoyed the limited nightlife, but the skiing tired them out as well and so they were not looking to party to the small hours.
IOf you are looking for a relaxed resort with good intermediate skiing and no long transfers - Claviere is certainly worth the visit!
