Packing Cubes: Listen, if Rick Steves says it, it must be so. (Okay, not entirely true, because if it was I would only travel from European country to European country via the insides of churches, but still, he's absolutely right about this.) I may or may not have watched his special on packing smart and I may or may not have come away a changed woman. These handy little suckers (available all over the interwebs) keep your stuff tightly squished together AND super organized. Whereas G's suitcase explodes, cartoon style, whenever he opens it, mine remains intact and holding a ton more belongings. You need these if you're packing light. Trust me.
Reusable Bag: There will come a time when you simply NEED to bring home an oddly puffy skirt (oooor, is that just me?) and there will be no room in your backpack/suitcase for it. That's when my trusty little friend, the reusable shopping bag ,comes in handy. Toss your souveniers into it, along with your purse or whatever "personal item" you carried with you on the way there, and just use it as a slightly BIGGER personal item on the way home!
E-reader: Listen. I constantly have this vision of me 1) reading for 7 hours straight on a plane and 2) sitting in, like, charming cafes perusing the works of Foucault. In reality, it never happens. Probably because I'm too scared of dying on a plane to read and also because I totally don't get Foucault. So, no more. Now I only take books on my phone or ereader--travel guides included--and leave it at that. I've also been known to scan guidebook pages and upload them to a cloud if an e-version isn't available. This opens up space in your luggage and also lightens it by like 12 million pounds.
Laundry Soap: If you're going away for 14 days, don't pack 14 outfits, just wash some of your darn clothes in a sink (OR at a local or hotel laundry - Makes for good people watching!). While I might pack a handful of sweaters I can repeat-wear, I won't pack a ton of t-shirts to go under them--rather, I'll just wash the underthings, along with leggings, tights, and bathing suits, along the way.(Note: George has taken this to the wrong extreme and will pack like 1900 vests and one pair of socks, rationalizing that he can wash the latter. Use your heads, people. Don't be a soggy-socked George.)
