I think it's the other way around (I've been on so many planes in the last 10 days they're starting to merge!), despite the way it looks on the plan. And I think that is just as well since 15A and 15K would otherwise have a line of sight into the toilet, but instead will be modestly protected by the blue curtain. So if I'm right, if you were to shift the blue hatching on the map downwards a few millimetres so that the toilets on the window side are inside CW-land (and the centre toilets outwith) then that would be a more accurate depiction.
