We fly in to SJO late and stay at a nearby hotel. The next morning we pick up a rental car and drive to the La Fortuna area where we will be staying four days. After those four days we drop off the rental car and use private transfers for the remainder of our trip (to Monteverde & Manuel Antonio).
My thinking is that it would be nice to have our own vehicle during our time in the Arenal area, but not as necessary in the others.
Does it make sense to do it this way? And if so, which rental car companies will allow you to pick up in Aljuela and drop off in La Fortuna?
