There is a reason certain travel habits get passed around by people who spend half their lives away from home. Flight attendants, frequent business travelers, and seasoned hotel guests learn very quickly that comfort is only part of a good overnight stay—the other part is control. That is why the towel-under-the-door trick has stuck around for years among seasoned travelers. It sounds almost too simple to matter, which is exactly what makes it memorable.

When you are staying somewhere unfamiliar, behind a door that opens onto a hallway full of strangers, even a tiny action can be strangely reassuring.
Once you understand the reason, the trick stops sounding dramatic and starts sounding practical. Let’s find out why and how…
