We are planning to stay at Selva Verde with our 17 and 20 year old kids after Christmas. Initially, we were not interested in a lot of travel and planned to stay there for a week. Upon reading reviews it seems people typically stay 3 nights or so. There seems to be a lot to do in the area but are we making a mistake by not travelling around Costa Rica a little more? There is a one day trip through the resort to Arenal to see the volcano and the falls that we would do.
