Costa Rica offers a variety of rental cars ranging from economy to luxury and I have rented from Vamos Rent A Car twice when I was at
San Jose. I felt their service was good and even you can get Costa Rica car rentals from Avis, Avanti, Alamo, Budget and Tricolor Car rental companies. They also offer cheaper car rentals in Costa Rica ideal for any occasion, so get a quote online and choose the one that suits your needs and budget. Many of the Costa Rica car rental services are based near the airport, so as soon as you arrive San Jose, you can rent a car. Even though Costa Rica offers variety of
transportation services for getting around like buses & trains, I feel renting a car is probably the best way to explore Costa Rica. Good luck!
