Line Your Suitcase with a Waterproof Bag
One of the worst things that can happen to your luggage is that it gets soaking wet. It’s nearly impossible to do the laundry unless you want to pay those super-high hotel laundry prices, and nobody wants that! The safest thing you can do is to line the inner walls of your suitcase with a waterproof bag.
Something like a trash bag will work just fine. Just cut it to size, tape the sides, and you’re all done! That way, rain or splashes of water while transporting your suitcase won’t cause your clothes to get waterlogged. Doing this is a tiny inconvenience that can be a real life-saver.
