>the implication was that some asshole can obtain photos of you sleeping by opening the curtains and switching on the lights in the middle of the night.

So, somebody is going to set up shop across the way, in what is probably another commercial building, commit a couple of crimes, all to take a picture of some random, likely unidentifiable person sleeping in a hotel bed?

Personally, I'm not very worried about that.

I mean, it's not like there aren't easier attack vectors for creeping on people in hotel rooms if you were so inclined.
