Would go along with Hans' suggestion about Turin and the Milky Way in that it's easy and cheap to get to. The 2 things I'd add though is that for aprés ski, you can't beat Austria. Was in Sauze d'Oulx (Milky Way) this year and wasn't impressed by the aprés ski (could have had something to do with the complete lack of Dutch who seem to be always up for a bit of craic). The other thing is if you book your hotel beforehand, the hotel may run a taxi service from the airport so check with them. We needed a bus, a train and finally a taxi to get to our hotel on the way out - only €15 but about 3-4 hours messing about. The hotel dropped us back to the airport - €30/person and 1 hour.
