We hired cars from National. Ordered over the phone
When we went to get them, they were NOT at the Geneva side like we asked but the FRENCH side so we had to get our stuff, and bikes through these very narrow barriers as we went from Switzerland to France inside Geneva airport. Then we waited an hour whilst they got petrol for one car then another 45 minutes whilst we waited for them to fix a puncture.
Then we got keys for 2 Citroen C2 cars HAVE YOU SEEN THE SIZE OF THEM!
F**Kers – we had to get 2 bikes plus kit plus 2 blokes into each.
We'd ordered Fiesta size cars knowing 2 bikes in bags would easily go in but we got stiffed. We managed to get the bikes in but basically had to wear our helmets as there wasn't room. it was that tight.
To say we weren't happy is an understatement.
The car hire company did exactly the same with a family of 4 (luggage and 2 push chairs) into a C2 won't fit.
Although car hire worked out cheaper than a transfer for us, I doubt I'd do it again as it nearly ruined our stay.
