I wanted to warn everyone about renting from Budget Rent-A-Car in Alajuela. They lied to me and said that you are required to purchase additional insurance to cover your rental and they forced us to purchase it. We already had insurance to cover the car; no additional insurance is needed. I couldn't prove this until I got home and when I contacted Budget about it, they said that location is a "licensee location" and so basically you have no recourse against them. I wanted to warn others so that you can avoid being scammed by them like I was.
I wish Trip Advisor would include car rental reviews so that we could add some accountability to these places, and maybe I could have avoided this company.
