It is important to store luggage carefully to ensure it does not become damaged, mildewed, or unusable if it spends a long time in storage in between trips. Generally, the best luggage storage tip is to empty everything out of the bags, nest smaller bags inside larger bags, and keep them in a closet or under the bed rather than in an attic or basement. This is because those areas of the home tend to experience more moisture than others, and it is easy for luggage to get damp, mildewy, and unusable in just a short period of time.
If at all possible, luggage storage should take place in the house with the rest of an individual's belongings. This is because the climate is typically relatively stable inside the house; not too cold in the winter or hot in the summer, and it doesn't usually get too humid. The same cannot be said for attics or basements, where significant temperature fluctuations and humidity changes are common. This can be made even worse if people decide to cover the luggage with plastic or store it inside a larger plastic bag. This is why closets or luggage storage under the bed is the best option, though it can take up a lot of room.
One way to save space when storing luggage in closets or under the bed is to combine as many pieces of luggage as possible. Generally items such as messenger bags or duffel bags can be flattened without doing any damage to those pieces, and placed inside a smaller suitcase. The smaller suitcase can then be put inside the largest, and it will then only be necessary to find space for that one piece. Removing any items from the suitcases ahead of time will help to ensure they can be stacked together, and will also ensure that nothing leaks inside the suitcase and damages it, such as toiletry items.
An option for luggage storage in the short term is to use a luggage storage service. These exist in some larger cities around the world, as well as places such as amusement parks or other common travel destinations. Individuals can check their luggage in and ensure it is locked up and safely stored while they explore a new city, for example. This can make the trip much more enjoyable, knowing the luggage is safe without having to drag the heavy bags around all day.
