Book your rental car with Expedia and you won’t have to pay anything until it’s time to collect your ride. It’s part of our convenient Book Now Pay Later option. Simply present a valid credit card to pay the cost in full at the pickup location. The car rental company will also put a hold on your card for the deposit. Cheaper deals may require you to pay upfront — how you can pay will be clearly shown in the search results. When it’s time to explore the best of Vienna, Expedia will help you find your ideal set of wheels.
