My Family (husband and two kids ages 12 and 9) are going to Costa Rica in February. We would love to try the ADR Adventure Park but my older daughter is very cautious and I am afraid of heights. From the pictures it doesn't look that bad. Any advice? If we don't like an activitiy can you skip it? Also - if three of us like it can the 12 year old follow allong without doing the activity. Thanks!!
