If the youngsters are the first priority then some of the eastern European resorts are good. The resorts in Slovakia are mostly small but ideal for beginners. Jasna has some more adventurous terrain. Slovakia is easily accessible from VIE. There are also some good thermal spa pools for the non-skiing days. You can also look at Bulgaria. In these places you can get good private tuition without needing a second mortgage. The instructors are not miserable like the ESF ones either. My daughter learnt skiing in Bulgaria at Borovets when she was 3 with a brilliant instructor.
