If you are young enough to burn the candle at both ends, then hit the slopes and bars at ST Anton.
Pretty much all you want there, if you can handle it lol..
The first time I went there I came back a total wreck...
You can ski from St Anton to Lech, which is the very posh part of the area, its very groomed there..
If you want a much relaxing trip then head for the quieter resorts in Austria, I still think it has the best apres ski and has some of the best scenery.
As Blessed mentions, some of the Austrian resorts are quite low.
