If your hotel room lacks a safe or you distrust it, the best strategy is to hide valuables in places that are inconspicuous or "dirty" enough that a thief wouldn't want to touch them. A classic 2026 travel hack is to hide cash or thin jewelry inside a rolled-up, clean disposable diaper; no one looks for treasure in what appears to be used baby waste. Other effective "low-tech" spots include inside an empty, washed-out sunblock bottle or tucked into the inner lining of a suitcase (between the fabric and the outer shell). Some travelers suggest taping an envelope to the underside of a desk or placing items at the very bottom of a trash can underneath the plastic liner. For more professional security, you can use "stash" products like hollowed-out hairbrushes or fake soda cans. However, the "Rule of Diversification" is most important: never keep all your valuables in one spot. Split your cash between your luggage, a hidden pocket in your clothing, and a secondary "decoy" wallet to minimize the impact of any potential theft during your stay.
