Hotel Laundry Service
Most of my trips are to Asia and last around 10 days in total. I travel with only a carry-on. I pack as much as I can but my job has me outside, on site, usually getting dirty. Can't stand flying in dirty clothes so off to the laundry they go.
Prices vary greatly depending upon the cities and the hotels. I've paid $32 to have 1 pair of jeans cleaned but have also had 4 shirts and 2 pairs of slacks cleaned and folded for less than $5. Either way, nothing beats that 'fresh' feeling before the long flight home.
