We did this in February of 2019. It's quite different from the version we did a few years ago. We went around the Magic Kingdom with a guide, stopping in various locations to solve different puzzles, and the solution to each puzzle led us to the next clue. At one point we also did the Ariel ride. Peter Pan came and helped with one of the clues (and posed for photos) and at the end we found Duffy and took him to Mickey. I would say it is aimed towards somewhat younger kids, so the 13 year old might find it too young, but the 9 year old would probably really enjoy it. In our group we had quite an age range though.
