Periodic reminder that if you’re in a hotel where the blackout curtains have an annoying gap and won’t stay closed, the hangars with the clippies are great at holding them together so you can actually get some darkness and sleep.
@TindrasGrove if the trolley of the service staff doesn't have mugs on it, how do you think they clean your coffee mugs? I always have a little detergent and a cleaning brush for dishes in my suitcases (next to the gaffer tape, a dish-towel, a suitable source of light and some other trinkets). Plus clamps for the curtains.
