"Compact little adaptor that acts as a surge protector. Unlike some other adaptors, this accepted both American and European-style plugs. NOT a voltage converter!! (Looks like this exact item may no longer be available; try a new search for it if you are interested.)"
"The picture doesn't do justice to how tiny and powerful this flashlight is. Great to have for when the lights flicker off in your hotel. Bring extras as gifts. (Since buying this, I've also discovered even tinier flashlights, basically the size of a large quarter, which I use as well.)"
"Travel soap, in dry form. I actually buy this at REI, but it's the same idea. Hand sanitizer only goes so far, sometimes you want to wash your hands, especially in skeevy public restrooms with empty soap dispensers. Goes without saying that I always travel with TP or tissues as well..."
"Use this with Starbucks instant coffee to make breakfast for yourself! Bring a travel mug if you want an American-sized cup of coffee, though, because the cups that are included are ridiculously tiny. The version I bought was 220 volt, which worked overseas; I just used the adaptor."
