Travel + Leisure: Thieves Always Check These Common Hotel Hiding Spots First—Here, 8 Clever Ways to Protect Your Valuables

"This surprisingly roomy portable lock box is the perfect pick for families, as there’s more than enough room inside for a number of people's valuables—and it’s far more reliable than a hotel safe. Just like most portable lock boxes, this one is secured with a three-digit code and comes with a lengthy adjustable steel cable that can’t be cut or broken. Despite its size, it’s incredibly lightweight at just one pound, so it’ll prove easy to travel with, and if you’re embarking on a beach vacation, you’ll be happy to learn it’s both water- and sand-resistant. If you’re traveling solo, this box is a great way to enjoy a quick swim on your own—just hook it onto the back of your beach chair with your phone and other valuables safely stored inside to prevent theft." - Travel + Leisure
