We'll be visiting La Fortuna for 4 nights in July and staying at Lost Iguana. We would like to have a rent a car (we are a family of 5) and I think it would make life easier. We'll be in Manuel Antonio before the Arenal area. We thought we'd get a shuttle - interbus?- to drive us from Manuel Antonio. Should we have them drop us off at a rent a car agency in San Jose so we can self drive to Arenal or should we have them drive us to a car rental agency in La Fortuna? While we in the Arenal area we hope to do skyTrek, the animal shelter, the hot springs, and go to Rio Celeste for a day. Thanks for your input.
