To put it metaphorically, it's like comparing JC Penny's to Bloomingdales. Yes, they are both retail shops that sell clothes, but it's an entirely different audience with different expectations.
And this is not really a dis against JP Penny's. I often find some decent clothes there, and the stores (often) look fine for what it is. But it's foolish to expect it to be like Bloomingdales... it's a different standard.
Every restroom needs to be redone or at least repainted
With the exception I mentioned in the front of the park, I think they have all been updated. The bathrooms behind the main gift shop are updated, by Apocalypse are updated, near Scrambler have been updated, and the ones by Twisted are being updated right now. Granted, that leaves Fort Le John and Katy's Kettle, but to me those aren't really in that bad of shape. The ones by Ninja are dated, but spacious--though I will grant you aside from the front of the park, should probably be next in line for a refurbishment. Then again, they are also probably the least used, so it's not as high a priority.
Every coaster needs to be running two cars minimum
As for this, I do agree with you... but I also just watched a vlog where a group got a behind the scenes tour of the maintenance shed, and they raised a good point...with 20 coasters, and each of those having about 3 trains each, that means at any given time there are over 60 different trains that have to be looked after year round. I can sympathize that's gotta be a
huge undertaking.
