Hello, we are a school group from Slovakia planning to visit Versailles on 6th October. We are 37 people, 24 children under 15, 3 students who are 18 and 10 adults. Can we book tickets in advance as a group so we can be placed in one carriage?
The train to Versailles isn't reserved seating so you can't book ahead of time for particular seats and carriages. If you take the Transilien L train to Versailles from Saint Lazare, you can arrive early for the next departure and should have no troubles all fitting into a train car as long as it's not evening rush hour.
Group ticket purchase & discounts are available if you wish.
