Seats are free, and you ask for them when you book
Child seats cost nothing and are never part of the fare. You choose them at the last step of the booking, and that is what puts the right seat in the car before it sets off for you. A seat asked for at the kerb is a seat that is not there.
Which seat your child needs
French law requires a child under ten to travel in a restraint suited to their size and weight, and the driver is held to it — a seat that does not match the child is a pickup that cannot go ahead. We fit three kinds: a rear-facing infant seat for babies up to about a year, a forward-facing toddler seat for roughly one to four, and a booster from four to ten. If your child sits between two of those, tell us their age and weight in the notes and we will bring the right one.
More than one child
Several seats in one vehicle is ordinary for us — most of our passengers are families arriving for a few days at Disneyland. Ask for one of each kind you need. Remember that children in seats are passengers: four adults and two children is a party of six, and that is what decides the vehicle.
If you would rather bring your own
You are welcome to, and some parents prefer it for a long stay. It travels as luggage and takes the space of a case, so count it when you tell us how many you have.
