Today I got the best hotel room tip (ever) to solve the can't get the hotel room curtains closed problem. From my friend Scott Brunner: "Most decent hotels have two kinds of hangers in the closet, pants hangers and skirt hangers ... Use a [skirt] hanger with clips to clip the curtains closed. It's not pretty, but I've done it, and it works."
Before checking out of the room, I tried it. It worked. Love it!
