Take in the master switch

In foreign hotels you will often have these system where one light-switch located right by the door controls the power in the entire room. It allows you to turn all the power off in your room as you walk out with a single switch and I am sure there are great advantages in terms of energy savings. The problem is that building designers and architects obviously are completely capable of working in the dark.
For example the hotel I am staying at uses this system which i'm all for except for the slight design flaw which is that the hallway light doesn't have a light of its own so the only way to turn it off is to kill all the electricity in the room. Now that doesn't bother you much while sleeping except it also means you cannot turn on your bedside light. Now even if that is something you can live with what I can't is that it also means you cannot charge your cellphone or computer at night which I found out the hard way when I grabbed my phone off the plug this morning to find it was 29% charged
