My family of 5 (3 kids ages 1, 6, and 11) are traveling soon to CR. We have private transportation from San Jose to our hotel near La Fortuna and then a few days later to Manuel Antonio. My question is: would it be best for us to rent a car while we are in the La Fortuna area so that we can get around, have a car seat for the baby, etc? Or is it best to just rely on tour companies to pick us up from the hotel and take us places? I am confused about this one!
