Might I be permitted to rave about Snowbizz. I realise that some of what I say won’t be seen as a positive for your situation but I’ll say regardless.
Me and the missus took the kids to Saalbach. We stayed in this hotel
https://www.ellmauhof.at/winterurlaub/kinderhotel-saalbach-hinterglemm.html
which currently costs around 6,000 Euros for a week for a family of four ( we paid a shitload less, £1,250 including flights and transfers, but I digress )
The elder kid skied with the recommended school. It was a disaster. The instructors were shit. He hated it and cried. We took him away, scarred.
Next year we took him skiing ourselves for a few hours. He disliked it.
And we got him private lessons in la plagne. He disliked it.
The following year they both did lessons in la plagne with the same woman. They disliked it. They knew they hated skiing.
Following recommendations from someone we tried Snowbizz the following year.
The resort is pretty small.
The accommodation was very basic ( though they have since added nicer options)
The apres ski is non existent
The resort is standard butt ugly french.
There’s very little advanced skiing.
BUT people go back because of 1 thing only. They encourage your kids to love skiing.
I still remember approaching our two kids ( who had almost point blank refused to get on the plane) after their first day… were they sad, we’re they tired…
Biggest, happiest smiles on the planet. They loved it. Completely transformed their view on skiing.
I can’t overstate how good they were. Our kids were pretty much bilingual when we tried in Austria, and subsequently did dozens of full day ski classes in Italy and Austria, but only because the awesome people at Snowbizz had set them up to love it.
(Esprit are the only other comparable company, but were way out of our price range)
Some of the kinderhotels are OK for later stages, but no comparison with Snowbizz
