Hey man, this mountain is about 5 minutes from my house. While they have a park, it is pretty lame. You are much better off going to Flachauwinkl (about 30 minutes away) because the park is way better in every imaginable way. Nicky Keefer filmed his edit from last year there, for what it's worth. To be that close to Flachauwinkl and not ride there would be a sad story to tell.
And if it happens to snow a lot during your time in the area, Alpendorf is ok but Zauchensee in Altenmarkt (where Atomic is based, also about 30 minutes away) is where you want to be.
