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.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

Ensure that you have a valid driving licence with at least one year of driving experience. If you are a foreign driver travelling to San Diego, an international driving permit may be required. Remember, hire rates can be higher for drivers under 25 or over 70

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

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

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.
