It is a fun program, and you can do as much or as little as you want as you tour the park. They may be a little young to do it on their own, but you can assist them. When you come in, you can pick up a booklet at the main station just over the bridge into Discovery Island. There are stations all around the park that you can stop at to do the activity, and you get a badge(sticker). Each one teaches a little about animals or cultural things. They do take up time, so we generally do the ones that coordinate with our plans.(I think there are about 30). If they like it you can do more, it if not you can stop and do more next time. DD has brought back her book on subsequent trips to continue filling it. Last trip we had extra time before our flight and were staying at AKL, so hopped over for a few hrs. mostly to get more badges completed. Enjoy!
