That queue would look better if they could block the natural light somehow (e.g., keep louvered panels to retain natural air but block light) to make the area very dim. Then use colored spotlights, gobos/light stencils, and projections to give the area interest and playfulness. And the overall dim lighting will hide the boring monochromatic environment, unattractive ceiling and fans, etc. The whole area could slowly change color theme, lots of potential to make the multi-hour wait more pleasant.
