Cheap AVIS Car Rentals at San Jose Juan Santamaria Airport, SJO

Inspect the vehicle for pre-existing damage and take photos to ensure clarity later.

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.

To save on refueling costs when departing from Airport, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.

If returning your rental at the airport, be aware of the parking policies and any fees involved.

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.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

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.

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.
