If traveling with children, staying in the 'Woodridge' area of Threabo is best.  It is right near 'Friday Flats' (a couple of minutes walk) which is the meeting point for all ski classes and ski school.  The main chairlift that takes you up the mountain is there as well, which means you can dash home for lunch and a rest before heading out again in the afternoon.  Saves money because lunch on the mountain is very expensive if buying for a family.
