What is the easiest way to play rotational gameplay?

I play aging off and I play one family one real life day. If there is something I want to accomplish then I play that family one extra day. I do this because I have only so much time to play and I want to play all my sims. I used to in sims 3 play my game and every so often quit the game and make a new family as I was bored with just playing one family. Now with the one day I get to play a different family every day and it keeps the boredom down for me. I also let them have a lot of free will so with this way I do not control the families so much.
oh and if I do not like the family or the direction the game is going I can take out that one family and it does not spoil my game.
