We used StartAbroad. Zach is excellent and we highly recommend him as well as the people who have helped us once we landed in Costa Rica.

It all depends on your credit card coverage. You really need to talk with your credit card to see what your options are. I always get all the coverage becuase I get nervous about the WHAT IF?...

Collision Damage Waiver (CDW) itself isn't technically "mandatory by name," but basic third-party liability insurance ("Responsabilidad Civil") is.

Most rental companies in Costa Rica bundle CDW into your quote anyway, making it seem mandatory because they won’t let you leave without it unless you can prove (with a letter) that your credit card fully covers rental CDW specifically in Costa Rica.
Even then, some agencies still require you to buy the basic liability from them.

I am in Guanacaste. Let me know if you are in my area and we can try to meet up. 🙂

I also suggest joining Facebook pages in the areas you are interested in to get more info and connect with people.

And hopefully people here will comment and share their experiences in CR. 🙂

Is it required to buy the CDW insurance they tell you That You HAVE to purcahse at the car renatl place? And if so Which insurance is best? I was there in December for 3 weeks and my car rental was only around $400 but with the ins. it was another $30 a day so another $630. They told me at the counter it is mandatory?

Thank you.
