Cheap National Car Rental Deals at Chicago Union Station, Chicago

If you plan to park at the station, check out the parking options and fees ahead of time for convenience.

Always keep your rental agreement, identification, and insurance information easily accessible during your rental period. This can help resolve any issues quickly.

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

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

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.

Planning to rent a car with National at Chicago Union Station but are under 25? No worries! You can still rent a car. Just note that rental companies might have additional fees and restrictions for younger drivers. When you search for a car, simply deselect ‘Driver aged between 25 - 75’ and enter your actual age.

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.

To save on refueling costs when departing from Chicago Union Station, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.
