laundry is so cheap--even if you're making multiple stops, they wash same day. we're talking going to laundry lady, not hotel service. We had nearly everything washed, ironed, folded for $7 US. 2 pr jeans, 2 pr khakis, all undies, 4 woven shirts, 4 tshirts, some socks. I know better now--and we each travel in one carry-on bag. Hotels have shampoo/cond and soap--email them if you're worried that they don't. I take small containers--hey, try shaving your legs/face with hair conditioner--it's perfect--silky and rinsable. All the other stuff you can buy sample sizes--don't open them beforehand and keep them in ziploc bags. No problems.
