We went skiing with Family Ski Company last winter and had a fantastic time. The whole set up is really well thought out for the family our kids really enjoyed it, meaning we did too! The childcare was second to none - our littlest one went to the nursery and settled really quickly, the 4 & 7 year old went to ski school where there was a helper on hand the whole time to help them along. Towards the end of the week we were all skiing together, which was amazing (as was the hot tub and the food back at the chalet!).
If anyone is thinking of going with them and has any questions feel free to ask - I would highly recommend them.
