It could be done with only a shallow ramp, however raising the floor 3-4' would affect the viability and view of the "balcony". There are three doors on the ground floor of the queue room with two being emergency exits (one leading toward the Enchanted Theater and the other leading to the left of the entrance facade) and the third being a balcony access door in the opposite corner from the entrance.
I'm a little hesitant with it right now due to these photos, though I do recognize the fact that this is unfinished and with all of the overhead lights on. What kind of flooring do you think they will go for? More laminate/linoleum like before or something else? It feels wrong to just leave it at the concrete. I have to wonder how long that post will stay up and if the park will request it be taken down. How often do we see an on-site contractor posting content like this?
The electrical plans show fixtures for six screens in the queue hallway (one to replace each bust). I'd love it if the busts could return, but unless something changes it seems unlikely at this point. I didn't see any connections for queue line FunTVs, but there is still a spot on the other side of the room for one.
