For those who have little ones who don't like the "line ride" at the beginning of most attractions or for those who hate waiting in queues themselves, spotting Hidden Mickey's is a wonderful diversion. We made small index card booklets listing all "confirmed" Hidden Mickey's in each park, organized by lands and attractions. They fit easily in a pocket or daypack and can be decorated with character stickers. We took the one for the park(s) we were in each day and looked for HM's in line or checked to see where we could find them once on the ride. An added benefit was getting to meet the numerous other guests who asked what we were reading and pointing at. This decreased the frustration of line-waiting even more.
