As you know, I have just returned from WDW.
Last November, I had no idea how this hub work was going to turn out. Two/three weeks ago, I was able to experience the almost completed project.
I walked barefoot on the turf, in 95 degree weather, and did not get burned.
I laid flat on that turf, and closed my eyes, just absorbing the sounds.
And just like the Soarin' building, I never once noticed a single light post, unless I looked for them. And considering that's not why I visit the Magic Kingdom, I can truthfully say that I was not conscious of them for more than 10 seconds.
