Do not use europcar if in a rush

Very efficient. There might be non-mandatory offers for insurance and vehicle upgrades, which you can politely decline.

The service was pretty good. Just needed to use the queue machine. The staff didn't push additional insurance too much.

The rental company was Europcar. They are a large company with good service.

Europcar is quite professional in Europe, slightly below Hertz. Their stores are large and professional, with clear instructions, which is very important and makes finding your car quickly easier (In this trip, we also used Avis for the third rental, and their instructions were unclear, taking us an hour to find the car, with average customer service and fewer car models, so we won't use them again). Many foreigners rent from Europcar. This is our second rental of the trip, from the airport. Due to a lot of luggage, we were first given a Ford business van (7-9 seats), but it felt too big for parking and maneuvering, so we requested a change (a very wise decision, given that the public underground parking garages have very narrow paths, making it easy for large vehicles to get scratched). The second car was a manual Hyundai sedan, but it couldn't fit our luggage (we could fold down the rear seats to fit the luggage, but that's not safe for travel), so we changed the car for a third time. After several changes, the front desk upgraded us to a manual Jeep for free, which was perfect. The Jeep handled excellently on mountain roads and steep paths, providing a safe driving experience. We returned the car at Avignon train station, which was very convenient, taking only five minutes. The clear instructions and ample parking space were helpful (unlike Avis at the train station, which had very few parking spots, no staff, and lacking designated parking spots could delay your schedule).

There is a dedicated building for car rentals outside Nice Airport, with several rental companies having counters inside. Europecar seems to be the most popular in France as the queue was the longest. We waited almost an hour to get our car. The staff, however, were quite friendly. Overall, we were quite satisfied.
