I dispute with my friends

We have a 'three star' room in a 'four star' hotel. This basically means that we get a cheap room, but cannot use any of the hotel facilities as they are stupidly expensive. One of the 'features' of a cheap room is that you get no window. This is not strictly true in our case as we do have a window, it just happens to be overlooking the bar!! Here is how to get some sleep in such an environment.
