If you’re anything like me, unpacking once you get home often takes as long (if not longer) than actually packing for the trip.
If you can, do your laundry the day before you leave your vacation spot (this works especially well when you’re visiting relatives).
Not only will you have clean clothes once you return, but it’s a way to make sure you actually come home with everything you either packed for the trip or purchased while on vacation. Once you’re home, unpacking isn’t so tough because alI you have to do is bring the bag in, put your clothes where they belong, and put the suitcase back in the attic.
