Cheap National Car Hire Deals at Washington Union Station, Washington D.C.

If you're traveling with pets, confirm the rental company's pet policy before booking. Some companies allow pets but may have specific fees or restrictions, so it’s best to clarify in advance.

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.

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.

If you don’t find what you need at Washington Union Station with National, you might discover more car hire options in Washington D.C., which can occasionally be cheaper. However, keep in mind that the additional cost of transferring from Airport to Washington D.C. might result in higher overall expenses compared to picking up your rental car directly at the airport.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.

Pick a time that aligns with your flight arrival to avoid any complications from delays.

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.

Ensure you know the rental office's hours to avoid arriving when they're not open.
