As suggested in the Buzz Lightyear's Pizza Planet (//http://www.photosmagiques.com/forum/viewtopic.php?f=1&t=8427) discussion, a dedicated topic for Videopolis.
First... the blackout blinds covering the windows.

Before Lion King, all those were open, looking out across Discoveryland. They covered them to allow LOTLK to have better lighting. So, are they meant to still be there?
Besides making it very dark inside (which is bad for energy bills too), they don't look very nice.
They might still be there to see the projector screen (playing old mickey cartoons) better.
