Yes, this is a little gem of a resort. Absolutely perfect for the beginner to intermediate skier. The layout of Margeriaz is logical and has plenty of blue runs that are actually fun to ski. My tip is the lower section of Les Coqs, which is an undulating piste through forest with some interesting bumps and curves. The pistes are maintained to a high standard.
Apart from me and my brother, I've heard English spoken here about twice in three years of visiting and although some of the instructors speak enough English to teach, you'd do better here with reasonable (understanding of) French.
Note that hotels are currently not available, as the Chamois is now owned by a ski club for its members and the Hotel du Soleil unfortunately burned down. There's no apres ski apart from buying cheese to take home from the dairy in the village.
