We have 2 goals in the arenal area: the arenal national park and proyecto asis. We are looking for a nice 3 night stay from where both tours can easily be made. We have found several nice lodges in the area (campo verde, cerro azul, finca nueva lodge) but we don't know if they are well-located for our plans. Can somebody advice us on this, maybe other suggestions? Actually we are planning to travel by shuttle bus. Or is a car much better? When yes, do we need a 4-WD or is a 2-WD sufficient?
