If you're like me, you hate any light that comes in through the crack in your hotel room blinds. I really like a dark room for sleeping.
On the other hand, if you're not like me, you might really care if somebody can see in your hotel room.
Well in either case, here's what to do if you're stuck in a hotel room where the shades don't close all the way.
Your keys (or a binder clip if you've thought ahead)
Take the split-ring from your keychain (aka a keyring), spread it apart, overlap the curtains and jam the curtains in between.
Have a good night!
