We were looking at Serre Chevalier for 2011, but have booked Les Arcs instead. Was 50/50 and Les Arcs got it because of the skiing (linked to La plagne so loads of options)
However, if your still open to other suggestions, one of my fav hols was Selva Gardina in the Dolomites. Great views, hardly any drunken brits, and vast amounts of intermediate/easy skiing – I was with the missus, so this suited her and caused no arguments 😆
The only thing about Selva and the sella ronda was i didn’t find anything very challenging for myself. If you were going to push yourself then prob get a guide to show you the best the reort has to offer.
