We are currently on vacation at WDW. Today we were in the Animal Kingdom and were stopped by a CM who asked our kids (10 year old girl and 8 year old boy) if they wanted to help out with a test they were doing. They are testing a scavenger hunt at the Animal Kingdom, where each person is given a worksheet that directs you to a place in the park and gives you a few tasks to complete at that place. After you are done the tasks you go to a designate place and show the cast member what you did in the area, and if it is done correctly you get a sticker showing you've completed that area's task. It only took about 5 minutes to complete the task. Once they were done there was a short questionnaire asking what we thought about the scavenger hunt. One question said "if there were 20-50 of these types of scavenger hunts throughout the park, how many do you think you would do?". Just thought it was kind of interesting given they seem to be doing a more interactive but similar type of think at Magic Kingdom, as well as having Kim Possible at Epcot.
