While looking over the Queue makes the ride thread I kept hearing about how boring the whole chain link switchbacks are. I realize NO ONE enjoys standing out in the boiling sun for a couple hours unless you are on a beach in which case you wouldn't be standing you would be laying down! SO.
IMO What Space needs is a little creative construction. Pillars, Satellites, Antennas, the works. Turn the outside of Space into a giant space station construction zone. Toss in some AA robots everywhere putting it together and there you go. Now you have some shade provided by a variety of structures. You have an addition/ enhancement to the whole Tomorrowland theme. AND you have something really cool to look at besides the glistening metal chains that burn your hand when you touch them. I would also love to see craters with meteors in them. Also I think it should look like you are walking on top of a platform... that can be accomplished by having areas open that show a planet/moon surface beneath you. Just another thought.
