Sorry, didn't see your original post. Guess you've already pushed off. Picked a nice snowy week to go, too. Pila has trees, which should help. Nice, little self-contained resort, which a lot of people reach by lift rather than by car. Pretty busy on weekends, very French in its design. Pila packs a pretty big punch for a resort of its size. Not much going on there at night, I don't think. You could always ride the lift down to Aosta and see what's up there. A week in Pila would not be a bad thing, though, from the skiing POV.
