Visitor Luke asks the question:
I have noticed that some rooms no longer have under-curtains/sheers at the windows. Why do you think this has been done?
My thought is that the various reasons for sheers have slowly gone away: privacy, limiting heat transfer, limiting UV penetration (which fades fabrics). Removing them makes the rooms seem more open, and provides better light and better views. And privacy isn’t much of a concern in the public rooms.
