Well various ghouls travel around the Wards, mine included so there is going to be some more people to interact with but also no one is restricted to a single ward. The main idea of the "Ward of Operation" is so we know the place your ghoul would likely spend most of their time.

On that note, I have a lore-related question. One I can't really remember from having watched the anime and read most of the manga quite a while back. 
Is there any kind of "border control" in between wards? Anything to physically separate them from one another? Or is changing from one ward to another like crossing a street? I don't think either version really specified, and if they did I don't recall it at all. I do have sufficiently planned out crossing borders with either of these versions, but I'd still like to have that clarified to avoid awkwardness.
