I wouldn't recommend Esprit myself. We went with them once, and it did seem to be full of families trying to offload their kids for the day, and evening sometimes. Their hotels seem to be a long way away from the ski area which means catching buses, not easy with children, and four lots of skis, boots, helmets etc.!
What we do now is book flights with easy jet, hire a car from the airport in advance, and book a nice hotel direct which is near to the slopes. I can recommend a few if you're interested. We have been skiing for years so we don't have lessons any more, and our children ski with us. When they were younger they went to ski school, but preferred to ski with us. I wanted them to go to morning ski school and then be free in the afternoons to be with us, but some ski schools only offer full day lessons.
Another option if you do need lessons is to book a private instructor. This can be quite expensive, but you could then book an hour or two a day, and all stay together. We did this when a friend came with us, she and the children had private lessons in the morning and we split the cost.
When we went with Esprit, we were initially booked into one of their chalets, until I found out that the children were not allowed down to dinner with us, and would have to be left in our room on their own. I wasn't happy about this and managed to change the booking to a hotel, where we all ate together.
I am like you, I like to spend time with my children when we are on holiday. If you want any specific advice about hotels or resorts, feel free to PM me. :-)
