Our family will be in Arenal for 4 days & MA for 3. There are several types of activities that we would like to do that are offered at both locations. For example, we'd like to zipline, see wildlife / nature hike, maybe horse back riding. Is one place better than the other for any of these activities. I already know we'll do hot springs, Cano Negro tour at Arenal. Beach and MA park while at MA/ I'm just not sure how to split up the rest! Thanks Again!
