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

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.

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

Check if the rental company provides extras such as GPS devices or child seats. These can enhance your experience but may come with added fees, so plan accordingly.

If you plan to drive off-road, confirm with the rental agency whether it's permitted. Not all vehicles are suited for off-road conditions.

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.

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.
