I'm not going to jump all over it. Prior to announcing Galaxy's Edge, I would have expected about half of what they did. The Staff Shops were long overdue, as was Circle D Ranch. In hindsight, Horticulture and Motor Pool should have been no-brainers, but I didn't see the options. Recycling and Pyro Storage were something I didn't have on my radar at all. Rerouting the DLRR and ROA were a complete surprise. MMRR caught me by surprise--and honestly, part of it was how it impacted people I know in Entertainment. The results are, frankly, mixed. I hear Tech Services got more room.
As far as clearing out the North Service Area, let me be a little more measured in my assessment (more thought, less pontificating). Until someone can show me how tearing down TDA makes sense from an amortization and write-down standpoint, color me skeptical. Any expansion back there is impacted by Pyro lockdown, and any proposals for tunnels face a lot of very expensive and logistical obstacles. I honestly don't know how much space they need on-property for staging merchandise and loading in-park delivery vehicles. Could they downsize 50%? Maybe. But I assume they are already running a JIT system from the Ontario warehouse. If they could relocate the Motor Pool to Ball Lot, then why didn't they do it for SW:GE? And if they can downsize backstage support for Entertainment, why didn't they do it when they moved out of N-19? If they can downsize the Parade Float Warehouse, how much and where do they put it? That leaves the TDA parking structure. Maybe they could build a structure on the Harbor CM Lot at Harbor and Ball (which they should have done two years ago) and run a shuttle to TDA, in addition to Harbor Point (which everyone I know is in favor of).
So let me make a good-faith estimate: Reduce Merchandise by 50%, Parade Floats by 25%, and move Motor Pool and TDA parking. But TDA stays--they can move some more departments off-site and put a few more Entertainment offices in there--maybe one third of the second or third floor. Maybe you move Parade Floats to where TDA Parking is. Best case--you might pick up the footprint of the Parade Float Warehouse, half of Merchandise Warehouse, and the two buildings flanking Pyro Farm. Functionally, however, I'm going to bet on one more ride for SW:GE, and that's it. But I've been wrong before.
