Rotational players - how do you play?

I play with the premades. I do stay in a neighborhood and world until I've rotated through all the families. Usually I focus on one or two of them who will get the majority of my time that rotation. The others I might just check in on for a day or two.

I mostly play with aging off, but every now and then I play with it on for just the current family. I don't have any set amount of time, but I do stay for any pregnancies or a full college term.
