Hotel Buttons: Good, bad, and ugly...

I recently stayed in a Marriott in Shanghai, where the light switches practically begged for some commentary. The good: text labels so I can actually tell what's going to happen when I flip a switch! The bad: it's still not natural mapping, which could have made it intuitive without resorting to labels. The ugly: the sticker on the Do Not Disturb button trying to tell you which way is on, but still not even being clear about it; plus, the "For Power Only" key card which defeats the power-saving function of using your actual room key. Still, I'll take this setup over Phoenix's mystery buttons!
