Could rather than doing mirrors, set it up so that people use displays that project themselves onto a custom background. Kind of a way of offering a connection to nature, or luxury without having to either go to or afford it, considering people are living in shoe boxes, on ships, and in stations. My webcam can do something similar with a software to remove me from the background.
So ultimately you are adding a sci fi feeling, and solving a performance issue.
