Cheap Europcar Car Hire Deals at Wien Rennweg Bahnhof, Vienna

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

Download offline maps or bring a secondary GPS in case the station's signal is weak.

Bring along your driver's license, ID, and credit card, as these are required for the rental.

Select a car that fits the number of passengers and luggage for a comfortable journey.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

Before finalizing your booking, check if the rental company offers free cancellation. This can provide peace of mind if your travel plans change unexpectedly.
