Here's a review of Pal Mickey, the wireless-enabled cuddly Mickey that rides on your belt while you tour Walt Disney World and tells you about nearby rides.
Mostly his little tidbits were not really helpful as the information he share was extremely general in nature. In fact, the only helpful information he provided was that a parade would start in 30 minutes. When he told us about restaurants he told us what kind of food there was which we easily could get from the posted menus. He never told us how long the wait was at attractions or restaurants. He did however tell jokes that were relevant to where we were. For instance, when walking by Star Tours he told space jokes. Another nice feature was that Mickey wouldn't talk while we were inside an attraction with the exception of the Indiana Jones Stunt Spectacular. Otherwise, he didn't interrupt and we couldn't force him to tell a joke or play a game which you can do by pressing one of his buttons at any time. Speaking of jokes, if you request a joke by pressing either hand or belly at a time when he's not given you the new information signal, he will not tell a new joke for 15 seconds. If you request a new joke within 15 seconds he'll simply tell the same joke again.
