Isn't there a web site with a character database as to when and where characters are located? My wife gets on "missions" to find certain characters. Any help would be appreciated.
I work in WDW entertainment, so I can tell you where certain characters are often found if you send send me a pm.
Once you are in the parks, any CM with access to a phone can call the character hotline for you and find out where any character will be on a given day. Their locations frequently change. Sometimes even *my* info is incorrect!
