We are planning a trip for early May next year. It is going to be my husband and I and our 2 kids ages 4 and 10. Our plan is to go to Arenal and than Manuel Antonio. But on another website I saw that for zip lining and canopy tours kids should be at least 6 years old. I’m afraid that my 4 year old would not be able to do most of the activities, or we have to switch with my husband. I would appreciate any thoughts. Thank you
