What is your budget?
What is your start point? How long will it take to get to the resort?
What type of accommodation do you want? Hotel with separate rooms or chalet style?
Why did you pick Austria in the first place? There are hundreds in Europe where you can ski
What level of expertise are your party? You'd need a resort with a good mix of runs to allow for that
Will there be any non skiers in your party. You'd need to go somewhere with things for them to do.
Will you behiring a car or relying on public transport?
