I've not spent much tim there yet, been busy costumizing the world. But, I did testplay the Totter Park(?) near by, by adding a few sales stands and activities for my sims to have more to do. I think the park will be my natural arriving point. When testplaying, the park has been quite busy and most NPCs have walked over to the funfair location. I never checked what those sims were up to afterwards though. Maybe this all depends on what lot is your starting point? A park will often generate lots of sims. If your arrival point is a residential lot, perhaps the hood's NPC crowd gets smaller?
