I don't put myself on a particular set-up for rotation, and I have noticed the times I have the most fun are when I play a household until a certain "event" is done. For example, right now I'm playing out a teen drama story where one of them started dating a boy that two other teen girls from different households are into. I'm going to play out how the other girls react to the breaking news and it will probably end mildly violent. :*
I'd say one of the most rewarding things about playing many households is that I get to progress the world in the way I want it to progress. Even though it did take a very long time to get a story going with everyone I care about.
