I will be meeting up with my parents in Tamarindo this weekend. I am seeing where many people are renting cars to do their exploring. Is it safe to rent a car from Liberia and drive to Tamarindo? I would be alone on that drive. I will be with them until March 29. We would like to explore some national parks and wilderness. Is a tour company a better option? I have driven in foreing countries before and am more worried about wasting money than anything else.
