I'm a big fan of packing cubes and folders. We're leaving Saturday to go to WDW for eight nights/nine days and since I know I'll be busy all this week, I went ahead and packed this past weekend. I'm pooh size and still managed to get nine pairs of capris/shorts and nine blouses in one 18" packing folder, which easily fit into my carry on. I also squished my panties and nightgown into a slim cube and my bras into another slim cube. I used a small Vera Bradley makeup bag to hold a battery charger, cell phone charger, and camera battery charger. I added a few other odds and ends in a small packing cube, packed two swimsuits and a coverup in another small packing cube, plus packed two pairs of flip flops, a Vera Bradley mini hipster, and still had room left in my 22" carry on. My husbands pooh sized cargo shorts were alot thicker than mine, but I was still able to get seven pairs cargo shorts, plus seven shirts into a 18" packing folder and nine pairs of underwear in a slim cube. I added two caps, a belt, a Handy Cooler fan, and a pair of sandals and again had some room left in a 22" carry on. I used to roll my clothes and use zip lock bags, but really prefer the packing folders and cubes. A 18" packing folder fits perfectly into a 22" carry on and you can squeeze alot clothes into those things and still have room left. As long as you can get the velcro to catch they will hold. I have a fear of the airlines losing our luggage and got almost everything into the carryons. We are doing only one checked bag and the only thing in there is another packing folder with my husband's extra three pairs of shorts and three shirts, a hanging toiletry organizer full of travel size stuff, another packing cube with three cans of sunscreen, and a hanging organizer to put our clothes in once we get into the room. On the way back, we'll put alot of the stuff from the carry ons into the checked bag. On the way down there I'm just a little paranoid about the airlines losing our luggage, so like to take most of our stuff with us in carry ons.
I got my original packing folders and cubes on Ebags, but then found them cheaper at a local luggage store outlet and also found some cheap at TJ Maxx. The Eagle Creek ones are the best.
