in certain hotels, I lay the the clothes on the ac unit to dry or hang out the window after rinsing(I know, ghetto)then I stuff in the laundry bags found in the closets with dryer sheets I bring for home

...works great for me but I did have a captain once lay out his running shorts and shirt on the airplane dashboard(I think that's what it's called) to dry. The flight deck smelled like a wet hamper, not the most considerate captain
