My experience is recent and very negative. I have reserved the car and also prepaid the recommended insurance and cancellation warranty. As I Olbia Airport, the rental company denied having to do with Holidayscars, saying they are just an outsider and there are no obbligations, that the purchased insurance was only a warranty for the deposit of additional € 1.200. In all I needed 1.670€ available on my credit card. The scarry side is that this deposit will warrant any kind of damage to the car. Besides, the contract called flex, foreseen the full fuel prepaid, which by the way is further surcharged with operational expenses and VAT, resulting into 3 times as much the actual cost of a full tank. The rental company required either the deposit above or to buy a new insurance. All in all it cost me 820€ for 2 weeks - outrageous. But most outrageous was the juggle and the scorn, not least the pressure of the rental company. Never ever will address Holidayscars. The terms & conditions are no way out to claim your money back.
