I'm a huge packing cube fan. I hate living out of a suitcase, so this allows me to 'unpack' while still remaining packed. Plus, I find that I can usually fit close to twice the amount of stuff in a cube.
Usually, each family member gets their cube, but I just heard a great hack: Pack by day, not by person. Put an outfit for Monday for everyone in one cube, then one for Tuesday and so forth. That way if you are moving locations, you can take out the cube of the day and leave the rest packed. This method also prevents you from over-packing because you are being intentional about what is going to be worn when.
