Try www.snowbizz.co.uk they have s/c apartments, the resort has a great reputation for sunshine and snow, we had a lovely sunny week once in March there and their creche and childcare team are amazing, definitely worth a look.
Have you tried kinderhotels Havent used myself but a woman at my dd's talipes clinic was telling me about their holiday a couple months ago and said it was fantastic. They have several skiing resorts I think.
We like to self cater - prefer the space and the freedom to do what we feel like and eat wh at we fancy.
Just before Christmas went to La Rosiere and had a fab time. Not least because DD was really happy in the lovely creche there. I know we were spoilt as it was a quiet week so there were only 3 or 4 kids in the creche with 3 nannies.
Being greedy I want a second (warmer!) ski holiday. I would return to La Rosiere but we found the area a little small for us.
Can anyone recommend a creche in a resort that we can book independently?
