I don't want them to change anything in the worlds - keep them as worlds with rental lots only - but allow players to change the lot type to any residential type. Granite Falls is one of my favourite worlds, and I've had Sims 'living' there more than once. It's so peaceful. I set my season length to a month and settle in my Sims for a long winter.
You can't have kids or teens, however, because they can't go to school, or have a career. I think you can now edit the lots without quitting the 'vacation', so that's helpful, at least.
