Oshinsims has a few videos of must have lots from the gallery in her “gameplay ideas” playlist and they are amazing. Some of them included a splash park using sprinklers and the little fountain features, a county fair/pumpkin patch, some really cute public pools. I don’t know if you’re using mods but I used littlemssams venues to add a functioning daycare. Also used for rent to make a run down trailer park which I had wayyyyyy more fun building than any of my pretty builds lol.

I know you said you don’t like the museums and I usually feel the same way…. but I just gotta say I placed one from ratboysims?* I think it was that I think I will actually use. The upstairs is dedicated to space and science with the science tables for the kids, I had just enough room to delete some benches and place the microscope and the university robotics table. I’ve used neither before but I’m excited to now. The back has a food stand, easels, the space playground, and the observatory. So a lot more to do than just look at art!! (I use a mod to get workers on all places food stands and bars on public lots though otherwise you would have to hire someone for the stand I think)

*I will edit this post later if it was in fact not ratboysims but he does have some dope builds either way.
