Pros: Watch out for extra costs when booking. We undertook a search from Lyon airport for 2 drivers and found a great deal with Enterprise.
However upon arriving in France we found the car was in the city not the airport, and had been priced for one driver rather than 2. The car was also an alernative DUV to the RAV 4x4 that we had ordered and was rather in the small side!
A good service otherwise but Kayak middleman caused incorrect booking details and an extra £100 cost.
