#5 in our Summer of Organized Travel is fitting everything into one suitcase.
Nothing says ease like a rolling suitcase. Think about bringing one carry-on and then a personal item like a handbag or backpack for the items you'll use in-flight. This will save you time in the baggage claim and keep things simple while you travel. Nothing says "tourist" like a giant stack of suitcases on the curb outside the hotel. Not to mention they're a pain in the rear end to wrangle.
