How To Pack Just One Carry-On For A Week-Long Vacation

Heading off on an island vacation? Lucky you! Here's one piece of advice to start off your trip right: Pack only a carry-on bag. You'll save on checked bag fees, won't waste precious vacation time waiting at the luggage carousel, and never have to worry about your luggage getting lost. Plus, if you need to fly standby or your flight gets canceled, you'll be able to hop on the next available flight.

What's that you say? You're going away for a week? No problem! Here's a step-by-step guide to getting everything you need into one portable bag, all without having to shell out for expensive packing accessories. Let's go!

The key to packing light is getting organized before you place even one flip-flop in your roll-on.

First, consult the weather forecast for your destination. Only sunshine during your trip? Leave the raingear at home — one secret to packing light is to only bring what you need, without adding "what ifs" to the bag.

Next, check with your accommodations to see what in-room amenities and toiletries your hotel offers. Hairdryers and irons are standard at most properties, so no need to pack them. If they don't have irons, leave items that need to be ironed at home.

Remember the 3-1-1 rule for carry on luggage (one 1-quart bag with liquids no more than 3.4 ounces). Avail yourself of your lodging's toiletries when you can (many luxe spots even offer poolside suntan lotion). Do, however, throw in some individual laundry packs or a small container of detergent so you can wash clothes on the go.

Now, before you put anything in a bag, make a list. Overpacking happens when you start grabbing drawers full of shirts and dropping them into your open bag (for a packing check list, see below). Write down every item you're going to bring on vacation.

Stick to a color scheme. A neutral background — think black, white, tan — with a few colorful accessories, such as a scarf or a sweater, will help limit what you're packing.

Wear your heaviest items on the plane. For example, if you're planning on hiking, wear your hiking boots on the way to your destination. For casual trips, wear sneakers and layers, including whatever outerwear you're bringing with you for cool evenings, such as a jacket or sweater. Basically, anything bulky that will take up a great deal of suitcase space should be worn (leave the sandals and shorts to pack in your bag).

Pro tip: When making your list, you should figure out what kind of bag suits you best. If you're not checking luggage, that means one in the overhead compartment and one below the seat. Look for a good, durable duffel bag or dependable roller that goes up top and a stylish backpack that stays with you. And be sure it's perfect for your laptop or tablet and headphones.

Okay, you have your list and you know what you're wearing on the plane. Now it's time to pack your bag. Consult your list and lay out everything where you can see it. Do not add anything to this. The secret to traveling with a carry on bag is to not overstuff. Now consider the most space-efficient way to pack each item.

T-shirts and shorts should be rolled to both save space and cut down on wrinkling. Start with a shirt face down on a flat surface. Fold the arms back so you have a perfect square. Fold in half vertically. Now roll up from the bottom to the top — voila, a perfect cylinder.

Heavier materials, like khakis and sweaters, should be folded into squares.

For lingerie and delicate items such as bathing suits, use mesh lingerie bags (you can find these at most drug stores), which will allow security to see your items without actually touching them and keep small items organized.

Dress up. For dresses, skirts, blouses or dress shirts, place each item on a hanger, and place in individual plastic drycleaner bags. This keeps clothes wrinkle-free (the plastic reduces friction) and organized.

Now you're ready to pack your bag. Stack square shapes first, then rolled items around those. Tuck shoes and flip flops into corners (and remember that shoes don't need to travel next to each other). Socks can be placed into shoes or into empty spaces. Place your toiletry bag on top of your perfectly folded clothes so you can reach it easily for separate screening. Then lay your plastic-wrapped dress clothes on top and fold it over to fit into the bag. Zip and go!

Pro tip: Even with just a carry-on bag, you should consider purchasing and using a set of packing cubes. By putting your clothing and accessories in these, packing is easier than playing Tetris.
