This YouTube video has received quite a bit of publicity since the Hampton Inn guest uploaded it on YouTube on November 8, 2014.
On the video, you can see the maid go through pretty much all the stuff that the guest has but she doesn’t appear to be stealing anything.

I never lock my stuff and usually leave my laptops out in the open when not in the room. I don’t believe that a maid would have ever stolen anything from me.
Few years ago, however, an overnight guest left with a MacBook of mine, but that was a bad judgment from my part and not the hotel’s fault.
