Now, granted, the park has a few of these...the Dapper Dans on Main Street, Laughing Stock and Farley over in Frontierland, Queenie and her band and the Bootstrappers for NoS. But why not really up the ante and deliver themed, interactive characters that are more spontaneous?
Frontierland could really, really do with a sherriff and a bank robber type, and staged gun fights like they used to do in the old days, or just to roam the land even if not in a show, or a old prospector type character for around Big Thunder or the riverfront, to speak in authentic frontier gibberish. Tommorowland could be a lot more distinctive with a couple characters, set up a Star Wars themed exterior set and have people out just to interact with guests...various Jedi, Sith, or Republic representatives, or a mad scientest type, as Maynard performed previously, lurking about the HISTA theater, given it's supposed to be an experimental science institute.
Adventureland doesn't have Indy anymore, but a couple of archeologists that switch off throughout the day, or a delusional jungle guide could be fun, talking to people and asking them about animals or pointing out artifacts in the land. New Orleans square could feature characters tied into the Haunted Mansion more, such as a "frightened" gardener or groundskeeper out front, or having a small show of one of the butlers or maids tending to the tombs and Pet Cemetary, adding a wreath of black roses, or flowers...something to make it feel more lived in, as the other additions throughout the lands would do. Critter Country could recieve a faux-naturalist and animal expert, to help locate Pooh and friends, if out, or deliver fake talks about the local wildlife (talking foxes and bears, singing geese, those country bears that dont come around anymore). None of these ideas are concrete, but something in this direction would be nice for the park...your thoughts?
