I'm just back from St Anton and it's wicked, crazy apres ski, way better than france. Big mountains, loads of steeps, the park is in another (linked) resort called Lech and is pretty good by euro standards.
If you do end up in St Anton (not sure where it is in relation to innsbruck) make sure to go to the Mooserwirt, it's the maddest bar in the world. Go in there at 5  and everyone is annihilated. However they are all middle aged and austrian, there are very few hot girls (in relation to the amount of men) in St Anton and those that are there are fiercely competed for!
