Some additional packing tips:

• Pack heavy items, such as shoes and toiletry kits, before the more delicate ones. Place them along the suitcase's spine to balance weight at the bottom.
• To reduce wrinkling, turn jackets inside out and fold them in half with tissue paper or dry-cleaning bags. Also, layering plastic bags or tissue between clothes, also helps to prevent wrinkles.
• Hang clothing in the bathroom while showering to steam out wrinkles.
• Line the bottom of your suitcase with your trousers and let the legs hang over the outside edge of the suitcase. Then pack the rest of your travel gear with the lighter materials on top. Wrap trouser legs over the pile; they'll keep their crease.
• Stuff socks and rolled-up belts into shoes to save space.
• Take along plastic bags for laundry or wet swimsuits.
• Bring an empty, soft bag for souvenirs.
