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.

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.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.

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.

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.

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.

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.

Utilize GPS devices or navigation apps on your phone to easily find your way. This can help you avoid getting lost and ensure a smoother travel experience.
