I just pack light and wash things in the sink because I was told that dry-cleaning and commercial cleaning processes are very carcinogenic and I have sensitive skin. Cheap hotel shampoo is not really any different from Woollite you know. And if the hotel is halfway decent, there is a blowdryer to finish the drying the next morning if need be. My friend finally stopped teasing me about my cheapskate habits when he learned that another friend of ours does laundry by putting his clothes in the in-room jacuzzi with a little shampoo -- whoo, talk about bubbles. No matter how frugal you imagine you are, there is always someone who will do it one better.
