I've had a bit of a crazy idea for a while now...not sure how the execution would work, but I've often read about the original communicore, and how it was supposed to be like the original main st., like people would walk through there to get to the attractions instead of right in the middle (in the heat and the "elements").
People have chastised the innoventions layout as it completely changed the areas, and also the checkerboard covering awnings that are in the center now.
So my crazy idea is that instead of having those awnings between the Innoventions areas, to have a glass roof above instead....tall enough to not interfere with the fountain of nations. Not sure exactly how this could be executed, but it would be a nice area to escape the heat/rain.
