Great experience with Hertz. Man at counter suggested an upgrade at a fair price so we did. Great car and made our holiday very enjoyable and safe.
It will cost you no less than $300 for a rental. I bought a flight once I arrived and they presented me with a rental agreement which was over 3x the cost of the rental agreement for which I had paid for.
Kayak did not disclose that Budget car rentals charges users per km after a very low free distance allowance. This can easily double or triple the charges upon returning the car. Kayak should disclose these hidden fees when displaying the options.
