Well depends what you want to ski. If you want to ski park you could go to Laax, Mayrhofen or check out the Allgäu Region (my home region).
There are a few smaller resorts but they are totally worth it.
Check out Fellhorn-Kanzelwand they have 3 parks and its a nice ski resort.
I am from Germany and if you want to know something you could just shoot me a PM or contact the member "Smuffy". He's on my friends list. He is an exchange student from the US and currently skiing as much as possible everywhere in Europe.
