From the grapevine, I believe there will soon be a Potter-themed garage in the coming years. There may or may not be an additional "Minion" lot as well. (this may just be a re-theme of CG, which is stupidly obvious now that I think about it)
Also: I like all the protection you guys did to make sure you, and your equipment didn't get wet.
I, too, walked around there about a week ago just to get the gist of the size of the area... and yeah I kinda felt like a creep. (except when I remembered there were a buttload of family/private restrooms in the back and shed a tear to know that they would soon be demolished) The stadium "parental" seating station seen behind Jon in the above photo seems to always contain bored teenagers on their phone while adults console and play with their children, so I felt very out-of-place. Though I've heard stories of employees going in groups into the ball pit and going to town over the years... smartly avoiding the chlorine-scented water play area. (too bad that's the portion making its way across the lot)
Universal Plaza's modest water play area (more like a larger, less wet version of the CityWalk fountains) will almost immediately slot in for CG but the sting will be felt for a little while as USH will have to deal with a tidal wave of complaints by frustrated parents that their child was only given a tiny dinosaur playground for seventy-something dollars until SSFL opens next summer. This won't be too harsh on GR, since HHN will scare families away and Grinchmas will have snow play. Spring break, however, will be rough.
