Another fan of the Amazon Basics packing cubes. We bought our original sets three years ago - through multiple trips (we cruise every April, vacation for 10+ days each July and then do a beach trip in August, plus various weekend trips throughout the year) - they still look brand new! We pack for three of us (DH, myself(an admittedly heavy over packer) and our 13 year old son in two suitcases for ten days with the cubes and still have plenty of room left over for souvenirs. We love that everything stays wrinkle free and compact - and you can unpack your suitcase right into hotel room drawers - just unzip the cube and fold the top back. In fact, my mom borrowed some of ours for our cruise last month and liked them so much that she was going to order her own, but we got them for her for Mother's Day. They are a fantastic investment.
