I've done it plenty of times in the past,and frankly when I don't I always find I've overpacked (I have too many clothing choices at home lol) One memorable trip was 2 weeks at WDW with one week being a hard freeze week.... we each brought a duffel bag.we layered,a LOT,and did laundry half way thru our trip- wish my laundry at home was so relaxing, by a lovely pool...honestly, if I have about a million tee shirts at home, I usually force myself to choose my favorite few to bring along,and I tend to rewear most clothes anyway(like shirts and sweaters) WDW is an easy place to pack for, since it's all 'civilized' territory with easy access to laundry if needed. I also now bring a foldable zip tote bag in my suitcase which I use as a carryon on the way home (which I usually need for my purchases)
