We all travel differently, and I used to think I'd never want to worry about laundry while traveling. I've flipped to the other side over the years due to a combination of having lost checked luggage and caring less what people think of my wardrobe while traveling. It's also taken me several many years to slowly accumulate a travel wardrobe of lightweight, technical fabric good pieces, usually bought on sale. We also usually travel DIY, so no one to heft my luggage around train stations and airports for me.
Then there's the mother of my BFF. We all went to France together for 10 days and she not only brought a different pair of shoes for each outfit, but an actual hecking IRON. My husband was appalled, partly because she assumed she and BFF's DH would carry her ginormous suitcase up all those tiny narrow stairs in our BnB's.
