Or have them live in the Humble Home, the house on the big island closest to the fishing spot with the waterfall. Sims gather there in the middle of the night, right in my sim's backyard, ON HER PROPERTY! I hear groups of them out there talking almost every night, and have to get rid of them. It's been the same every single time I've had a family in that house. I even fenced it for her and locked the gate to everyone except her, but they still congregated in her bakyard! It's SO annoying! But you could wake your sim up and send him/her out to meet them. LOL!
