We used this on a Guide indoor weekend with a Harry Potter theme. We split the girls aged 10-14 into 5 teams of 3/4 and set them off with a 3 minute delay between each team. We had 3 rooms with an adult and two of the story elements in each room that they moved between them. They all really enjoyed it and it took just over an hour for them all to finish. The initial printing and setup took longer than expected but I was doing 5 groups. We will definitely get another one for our next camp/holiday.
