If you take a direct flight to Italy from Doha, you have 2 alternatives: you land in Milano and then you need to rent a car, either to go west or east (both cases about two hours to reach final destination)or Rome, and then domestic flight to Torino (east) or Verona (west)and you are quite close to the mountains (again you have to arrange for transportation from airports to hotels,unless you agree on a package with the resort you choose, in this case they will pick you up at the arrival).Since you have children, maybe the suitable places are Bardonecchia (valle di Susa),or Gressoney (valle d'Aosta)both in Torino's area,or Val Gardena (verona);if you really want to go skiing,with real snow, I suggest you check in advance: you know, nowdays snow comes at heaster time, and you might be disappointed not to find any at christmas!!Let me know
