What is the easiest way to play rotational gameplay?

For me, it's aging active family only, with NPC aging on, and a regular rotation schedule, sim time. I used to give them each a week, starting on Sunday at around six am, but now its four weeks so they can have all four seasons, starting with the first day of spring. The upside is that I spend more time each family and get more accomplished, the downside is that it takes forever to get through all the households.
