The Day-0 sequence
1. Name the product before you pay for beds
Creche and halte-garderie hold the under-3. Ski kindergarten / Piou-Piou / jardin is usually from 3. Group ski school is a third product. If you book "kindergarten" for a 2-year-old, you have not booked care. The decoder for those three words already lives on ski-school-vs-kindergarten-vs-childcare.
2. Day 0: beds and the named care slot together
This is the sitting. Open the operator page in the local language. If a visitor creche prints your age, book that slot before you congratulate yourselves on the apartment. We do not hold a Christmas sell-out number. What we hold is "places limited" and "book before you arrive" on named pages.
3. Then the named ski school
If the child is in the ski-school band, book that school next. Of 141 starting ages we already hold, 86 start at 3. That is a library, not a law. Confirm the named school. A Saturday arrival can still miss Sunday morning if the school wants a Saturday desk check-in.
4. Then the pass
In the files we hold, the pass is not the scarce Christmas object. Buy the ticket that matches the mountain you can actually reach, after the care slot is real. We will not invent a holiday lift sell-out.
5. Then the transfer and the child seat
This is the Saturday trap nobody budgets. A private van and a shared coach are different products. Read the operator page for that airport. Request the seat if the operator offers one. Bring the booster if they tell you they do not provide it. Do not assume the cheap Geneva coach will take a toddler.
