I'm interested, too. But from my understanding so far (without having the pack yet), I'm planning to play a full term (5-7 days) without rotating, and with aging turned off for everybody. Then the student must enroll again for the next term, but I think there is no problem to wait with the next enrolling. Game will not push a non-enrolled student forward, so next time playing the student I'll enroll + play through 1 term.
This way I believe rotating between houses is no problem. It will even be cute if the student visits parents between terms. I need to find out what happens to their dorm room if they take a break to visit their hometown, though.
Added: uhuuu, just read the post by @babajayne - if breaks are too complicated, I will rather play my students through the full thing with aging off, but limit how often I will send students. Would be so much easier if we could switch households between terms...
