We did it on our last trip and enjoyed it. DD6 had a great time helping read the map and figuring out the clues. Be prepared for a lot of walking. You're all over the park, and you have to do things like act like your favorite character, skip, etc., on your way from one clue to another. We met some characters along the way and then had a special meeting with two characters at the end. I think it's probably most fun for kids 4-9 or so. Any older than that and they might not be as into it. Have fun!
