So far I've replaced Waterside Warble with a café and filled the apartments in San Myshuno with a slew of Sims I'd made and placed in my Gallery. I'll see if the new locals will check out the festivals, and if some Sims from other worlds will visit the café, discover the delights of the city, and decide to come back for a festival. So I took your idea, @Gagea , and turned it up to 11.
I use a mod that keeps Sims from wandering randomly out of their home world, but I've discovered they will still sometimes visit bars, clubs, spas, parks, and cafés in other worlds. So while the Landgraabs don't jog past my house in Newcrest 38 times a week, they'll still take a yoga class at the spa around the corner. Perhaps the premade gang will visit the new venue in the Spice District.
@BoergeAarg61, I think I'll combine your idea with @"Inna Minnit" 's. If I rotate through a few more households, I can have them create some kind of club that hangs out in the city, doing city things.
All these suggestions are really good. Thanks for sharing them!
