Best Resort for children (Europe - Austria, Italy, France, Switzerland?)

Hello everyone, my children have just started their skiing journey this Feb at a super last minute trip that we booked to join with friends - we went to Scheffau, Austria and the kids joined the Kinder Kaiserland and Ski School there - they loved it and were going down the blue slopes by day 4. We are now thinking of next year's half term and although tempted to just go back to Scheffau was wondering if anyone here has any good suggestions? Key points:

It will only be the kids skiing and I am taking them alone
They complained a bit that the instructors were talking too much in German so def a school where the instructors are fluent in English
Apres ski etc not that important as I can't imagine doing much of that with a 6 and 8 year old hence we would much prefer an easy, family friendly resort where lifts are accessible and food is taken care of
Main requirement is a good ski school/instructors - I would rather save our budget for that than fancy accommodation

Any ideas? Restricting it to Austria, Italy, France or Switzerland as I need to narrow down the options :)

Risoul is very good for small kids

Thanks Dobby any particular hotel or ski school that you recommend?

Not many hotels that I know of, I'm afraid. We went self-catered. Kids (then aged about 12 and 10, I think) went with ESF, which was OK.

Sorry, Karolina, I didn't spot that you are going at half term. Risoul may be busy, depending on French half term dates. Italy is usually at UK half term, but check for Italian Carnivale (sp?) dates.

Hi Karolina,
I would suggest the Italian Alps of Gressoney with its 3 valleys. Champoluc, Gressoney and Alagna.
Great ski slopes for different kind of abilities. Great hotels in all three resorts. Nice people and great food. What do you want more than that :-)
If you need any help... I am here.
Ciao
