From my own experience, this _sounds_ like a good idea in the beginning, but turns into a real mess, as it allows you to never quite wrap up at the place you're moving from. Now, since you're moving from your parents' place, this burden might not be nearly as heavy, but I think the incremental move allows for the possibility of putting off indefinitely what you think are little tasks -- cleaning out the bathroom or the back of the closet -- but that turn into real bears when you're tired and you just want to know where the shampoo is. So watch out for the inclination so think, "Aah, that'll be easy, I'll take care of that on the last trip."
