There is no window by the door as its inside corridor. Back is a sliding glass door with railing if above ground floor on wing rooms, patio if ground floor. In the tower it's a slider to balcony above ground floor or to patio on ground poor.
Are you talking about what the sliding glass door in the room looks like? It pretty much goes the width of the room, with curtains at either side that you pull together to close. If you are in the tower, the slider leads out to your balcony. If you are in the garden wing on the first floor, it leads out to a patio, and on the upper floors it opens to a railing so you can get fresh air.
When you walk into the room, the slider will be on the opposite side of the room.
No one will see your decorations because the CR has interior corridors. And they ask that you not decorate the doors at the resorts with interior corridors because it increase the combustible load in the corridor (and you need the corridor to exit during a fire).
