Roland Garros. A stadium in the Bois de Boulogne, with a security line around it.

The stadium sits inside a perimeter. Spectators pass through one of three controlled entry points at Auteuil, Molitor and Boulogne before they reach the grounds, which means a car sets you down outside the line and you walk the rest. Knowing which checkpoint matches your ticket saves a great deal of walking, because the three are a long way apart on foot and the approach roads are one way in places.

The traffic pattern is predictable and unpleasant. The roads feeding the Porte d'Auteuil, and the Boulevard Périphérique alongside them, fill in the hour before the day session and again at the close of play, and the night sessions on the main court can finish very late. We plan movements around the session times rather than the match times, hold the car somewhere sensible between drop-off and collection, and agree a meeting point that still works when the whole session empties at once. Cars in Paris are arranged through operators we know, to the same brief we give our own chauffeurs in London.
