We are going to Arenal and Manual Antonio the first week in April. I've booked a 4WD vehicle, but wonder if I need one if these are the only two places that we are going? The 4WD is much more expensive than other cars, so I'd like to downgrade if that's advisable. We want to do some exploration between Arenal and MA but would not likely be going too far off the beaten track (though how "beaten" the tracks are remains a mystery to me, which is why I pose the question!).
