I'm gonna have to correct a few things in this post.
There is indeed a park at Hintertux.
Zillertal is the whole valley, not just one resort. The park you refer to as the Zillertal park, is probably the Mayrhofen Vans Penken park, and it's one of the best in Europe. However, it probably won't be open this early. The lift you refer to as the Zillertal lift is probably the Penkenbahn, which leads into the Penken ski area.
With that being said, I would personally go to Hintertux, Kaunertal or Stubai. They're all glacier resorts, and should have the possibility of pow, even this early on. Please don't go to France, the mountains are amazing, but the resort towns, and the people in them often make it a subpar experience. For the whole package, Austria is the way to go. Sweet mountains, picturesque towns, nice people, good food, and relatively cheap beer. And above all else, the schnapsel! Go for marillen or obstler.
