Yes several things, All my clothes are lightweight and quick dry. Clothes from places like Lululemon and Rhone for men are mostly all light weight and quick dry and nice looking. I also stay in airbnbs unless just one night as I find in the end I save by having breakfast home and some takeout meals. I always get one with a washer at a min. European Airbnbs often don't have dryers but racks for drying which with quick dry clothes dries overnight while I sleep. All my clothes can work with each other meaning I limit colors and take mostly neutrals which can mix and match easily. All of this has help my H and I pack much lighter than in our ealier trips.
Added note.. I just read through all the above posts so nothing I said is new.. sorry.
