Lovestruck sims spawning on all lots?

Just wanted to add that I spent the last two hours experimenting. Temples always spawn two couples. Parks never had less than two couples. If I went into a parking lot during the hours where children do not spawn there would be as many as five couples.

The only way to not get couples is with the singles lot trait. But this would lead to a near empty park. As those Sims walk around the lot and don’t actually enter.

The best way to achieve a somewhat pre-lovestruck park experience. Is to load into parks weekdays after three but before seven. Or during the day on weekends. But this will still give you at least two couples doing the stargazing animation.
