I look at it the same way I look at Sea World right now - I realise that most of SW's works aren't attractions, but they are incredibly disruptive - especially to guest flow, having to go "round the world" to get to everything.
Its a necessary evil, and I think the parks will be better for it when it is completed, but it's really showing the weaknesses in park flow and design when these attractions \ paths are closed. It shows precisely why Arkham needs chinatown alley, instead of scooby's backdoor. It shows precisely why the park needs CLEAR signage at each location (yes I know, guests won't read them and complain anyway, but still)
Given Superman's main walkway has a covering between path and track, it begs the question - couldn't they have kept the barriers open so people could access AA, except for when they actually have trackwork scheduled? If the trains are out for maintenance and they're not working on the external track, theres no need to fence it off.
And worse - if we can open chinatown alley to access AA when superman is undergoing maintenance, why can't we have that section (at least) open all the time? It's almost #SeaWorldGateGate all over again.
