The most expensive games in history? Even volunteers can no longer afford Paris. The average price for an overnight stay in the capital in July and August is around 1,050 euros per night.

The costs for the volunteers will also be difficult to cover in the wider area surrounding the capital. In order to avoid the high housing prices in central Paris, many of those helping out resort to the cost-effective alternative of camping. France's National Olympic Committee is looking for further solutions to accommodate those helping.
