This is so easy. First, go to AAA. If you want, you can do the application in advance… but it really only takes 2 minutes to fill it out.
Be sure to bring your drivers license. You will need two passport photos – some AAA offices will do it for you! Pay the fee (it’s $20) and they’ll get you on your way in no time. Easy peasy.
Quick note, the license is good for a year from your departure date.
