PLEASE SUGGEST: A Family Skiing and NY Holidays in Austria/Italy/France/Switzerland.

I would suggest you stay in St Christoph (that's your "50% quiet") with a good ski school on the doorstep and access to the whole St Anton/Zurs/Lech area, and party in St Anton which is a 30 minute ski away (including the uplift) and a 10 minute taxi ride home.
