Hi Headless - are you thinking about the Chalet Hotel Des Deux Domaines in Belle Plagne?
We stayed there last year with DCs who were then aged 4 and 8. There was an entire range of ages there - from a few months old to teens. Obviously, the creche only looks after children up to 11 (I think...)
The day runs like this:
Drop DCs at either creche (for tinies) or boot room, all fully dressed up for class, where nannies will collect them. Even if going to creche, you need to take outerwear for them as they get taken for walks, go out to make snowmen etc
They are escorted to ski school, nannies watch the classes and then return to hotel with children.
Children have "supervised lunch" and then return to creche (aka "Snow Club") for indoor or outdoor activities.
High Tea is served for them at 5.30pm. Some parents sit in with this. Others collect at around 6pm.
Am assuming your eldest DC won't be skiing so you will sign both into creche at 9am and then return to collect at 5.30pm/6pm. Unless you only book half day childcare in which case you can collect them at 1.30pm when they have finished their lunch.
I was very nervous about the set up the first time we used Esprit (3 years ago). Was concerned about how the DCs would feel being left, if they would have all needs attended to etc (my youngest was then 3). However, my DCs have generally had a brilliant time (except my eldest DC was a little bored in Snow Club - being one of the eldest at 7 and 8).
We book them in for all childcare options but in reality take them out for most afternoons - even if its just for a quick swim at the hotel pool. I have to say, it is nice to have the option to have an afternoon alone with DH or to myself But I don't think you can select specific days - you need to book for all afternoons or nothing, iirc.
You will find a mix of parents - there will be those who drop and run early enough to be on the first lift, telling their (sometimes screaming) DCs to pull themselves together.......but the majority are just as concerned as you would expect them to be and make an effort to get to know the childcare staff etc.
The creche at Deux Domaines is very nice. Bright and light and the staff last year were fabulous. They also offer a baby listening service - there are 2 nannies per floor who either listen at door or go in room to check on children whilst you have dinner.
