We rented a 4 wd Subaru from Hertz via Kayak. The car was perfect for our ski trip; the agent in Geneva extremely helpful; and the price was the lowest we could find anywhere.
We flew into Geneva airport and the car was located at the train station in the Centre-ville of Geneva which is a three mile trip by public transportation. Carrying our skis, boots and bags for 9 nights was a pain; however, the cost savings made the inconvenience worthwhile.
