After many years of travelling and staying in numerous hotels, I WISH someone would educate hotel bathroom designers what is necessary for women to apply makeup - a magnifying mirror and lighting that lights up a woman's face so she can see in detail to apply make-up. Overhead lighting and lighting that comes out the side of the mirror are not appropriate!!
I also would greatly appreciate soundproofing rooms - between rooms on one floor (bathroom sounds - showers and toilets, noise that penetrates between rooms) and between rooms on floors with rooms above and/or below another floor (especially for people who "stomp" when they walk or children running and jumping within a room).
