Just saw this on the internet. While Marriott is not mentioned (thankfully). It's alwasy best to abide by the suggestions mentioned at the end of the article. Safe travels!
Thank you for posting this. It's a good article and an important post and reminder in terms of personal security, especially for women or anyone traveling alone. Even if this specific breach were to be fixed at all hotels, criminals will just find new ways to get into hotel rooms undetected. I think this is a good reminder for all of us to get into the habit of "clearing" a room (however possible) when we first enter, to ensure personal safety. It's also a good idea to be aware of our surroundings. If anyone has any good ideas or tips for personal security or clearing a room before shutting the door (short of conceal carrying, which may be an option), this would make for a useful discussion. How do we enhance our personal security when traveling? Maybe getting a license to carry Mace might not be a bad idea. Once, my dad bought my sister and I each a device that produces ear splitting sound at the push of a button. I'm embarrassed to say that I lost mine. But it was loud, even too loud to demonstrate.
I think a lot of "better" hotels have hallway cameras, but I doubt that they're monitored in real time. Probably just taped for future reference. As far as property crime, I'm not comfortable leaving any valuables (jewelry, electronics, etc.) in a room that doesn't have a safe big enough to store all valuables. I wouldn't leave valuables in a room any more than I would pack valuables in a checked bag.
