Everything was very straightforward, I

Everything was very straightforward, I was asked to buy additional insurance by Avis for breakdown etc, so it would have been useful to understand this wasn't included in the quoted price - if it was stated it wasn't obvious. It would be useful for you or the rental companies to provide more information on how pick up and drop offs work at the specific airports. Finding the drop off place a San Francisco was not great, as the address stated and google maps puts them in slightly different places - and the attendant joked that finding the garage wasn't easy.

 What do I need to do when picking up a car?

To pick up your car, you will need your voucher, passport, driver's license and a credit card. It is very important that your driver's license and credit card are in the same name as the main driver. Keep in mind that the local rental company will reserve a certain amount on your credit card as a deposit. This requires the PIN code for your credit card. If your driver's license is foreign (for example, in Chinese), you must bring a translation with you. Only your original passport and driver's license will be accepted - a copy is not sufficient.

 Are there any additional costs?

In general, our rates are all-inclusive. Should there be any additional costs, our booking department will get in touch with you before issuing the invoice. Should you object, you can always cancel your reservation with no obligations attached (at least 48 hours in advance).

What kind of insurance is applicable to my car rental?

In general, Liability Insurance, Fire Insurance, All-Risks Insurance and Theft Insurance are included in the cost of your rental car.

 What is a worry-free label?

Only rental companies with a high level of customer satisfaction are eligible to be included in our Worry-Free selection. This rate includes excess cover and unlimited kilometres. Your vehicle will be provided and must be returned with a full tank of fuel. With a vehicle from our Worry-Free selection, you can travel with peace of mind and no hidden costs.

 How can I change or cancel my reservation?
