Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

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.

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.

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

Note that some rental companies impose age restrictions or additional fees for drivers under 25. Always verify the age policy when booking.

Look up fuel prices in the area where you'll return the vehicle. Refueling at a local station is often more economical than paying rental company rates.

Before leaving the rental lot, inspect the vehicle for any pre-existing damage and ensure it’s recorded. Taking photos can help avoid disputes upon return.

If you're traveling with pets, verify the rental company's pet policies beforehand. While some allow pets, there might be specific fees or limitations.
