The swanky hotel I stayed in on Central Park South last weekend had a lighting system like a symphony.
The room was NYC-size (that is, small), but had no fewer than 9 different kinds of lights. The light strip over the bed (above) spontaneously changed color. The one under the bathroom sink (below) was activated by my feet when I walked into the bathroom. The bedside lamps had at least four settings.
None were controlled by a simple on-off switch. You press a button, and wait for the light to slowly fade or brighten. There is a lag between the moment you press, and the moment something happens, so I spent a lot of time impatiently hitting the switch. Sometimes it faded and brightened repeatedly, with no apparent off setting. No exaggeration - it took me 15 minutes to kill all the lights. Finally, it's blissfully dark and I crawl into bed.
Five minutes later, there is a knock on the door.
It's a room service person, delivering a cute little late-night snack tray: an apple, a plum, walnuts, dried fruit. I was just thinking that I was a little bit peckish, but not hungry enough to order room service, so I'm tickled by the unexpected treat.
Except. When I shut the door behind him and turn around, I find that all the lights have flipped back on again.
Apparently, just opening the room door triggers the light symphony again.
