If you like big wide empty pistes go over towards Tignes. I didn't stay awake much after tea time. I imagine there's plenty going on tho', and, to be fair, I suspect the exchange rate helps prices more these days. The skiing at Deux Alpes goes high up so you can usually find decent snow somewhere. Looking at a piste map there appears to be a decent variety of green, blue and black runs with limited reds, but to be perfectly honest, they're all pretty similar.
Beginners can have fun up on the glacier where there are some good wide runs to build confidence.
Whilst up on the glacier take a look at the ice cave which is most impressive. Pretty cheap beer - just over 2 quid for a half litre, and reasonable food. Many of the smaller restaurateurs don't understand english - or maybe it's just me, but they're all friendly enough. It's definitely a good place to be self catering. The village isn't picturesque but it is fun.
