In my experience there are never enough towel racks or they aren't wide enough for the towel and the bathroom ventilation is usually set to stop automatically when you close the door.

Hotel electronics do not have feelings so I don't really think that the monster qualification applies, and they are probably ok anyway as they are so rarely used and have time to dry before being powered on thanks to the aircon helping maintaining a dry air. I don't think the actual electrical components do suffer from a lot of moisture from the towel.
