I have no problem washing clothes in my hotel room sink to save time. I've been doing this for many years.
However, occasionally I stay in a hotel, usually the ones on an RS tour, where even after two days the clothes don' t want to dry. I wring them out, roll them in a towel , and hang them up. Quite often, I've had to use the blow dryer early in the morning to finish drying a pair of socks--and I wear Smartwool.
Have any of you found any other techniques that might help to get the clothes dry besides going to a laundromat? You can also assume there is no outside clothes line.
By the way, if a room I'm in has a towel warmer, I'm a happy camper.
