I hope the parachute training center does not get removed, and perhaps will finally get greenlit for replacement of the mechanical hardware. Even if it never reopens, maybe they can use it as a Giant Christmas Tree during Winterfest again.
I would watch where the new path got installed between the Golden Kingdom and Plaza de Carnevel (El Toro). When they took dow the Saw Holoween maze, they also finally removed the long abandoned water play structure behind it. Maybe they just finally decided to sell the scrap metal, but the path to Kingda Ka really could use more animation.
Perhaps a new show in the amphitheater next to the Wild Walkway? They do have the expertise at Discovery Kindom to put on an okay educational animal presentation. The whole Wild Walkway area could I use a refresh, especially with the loss of Camp Aventura.
Perhaps the old plans to make the Bamboons viewable from in the park could be dusted off? (I am sure I saw that in an old press release or interview, but could not find a reference for it in my two minutes of searching.) This could be accomplished with a short path from Zumanjaro: Drop of Doom, perhaps with a path built down to Medusa to get rid of both dead ends. And lots of plexiglass to protect guests from objects thrown by the Bamboons.
