When selecting insurance, consider whether it includes free excess coverage. Free excess means you won’t pay a deductible in case of damage, providing additional peace of mind. Compare options to find the best fit for your needs.

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.

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 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.

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.

Most car rental companies will ask for a credit card deposit, which is usually held temporarily. Inquire about the specific deposit amount and the process for releasing it once the rental is complete.

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

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