Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

Familiarize yourself with the fuel policy for your rental. A 'Full-to-Full' policy means returning the car with a full tank, while 'Same-to-Same' indicates you return it at the same fuel level. Full-to-Full is usually more economical.

Before you finalize your booking, see if the rental agency offers free cancellation. This can be helpful if your travel plans change unexpectedly.

Select a car with good fuel efficiency to save money during your rental. This can significantly reduce your overall travel expenses.

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

When selecting insurance, consider if it includes free excess coverage. This means you won’t have to pay a deductible in the event of damage, adding an extra layer of security.

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.

If you're looking for more comfort or features, inquire about upgrade options at the rental desk. Sometimes, upgrades are offered at a discounted rate at pickup.
