Yea the building complex is definitely just a shell now. There's honestly not much of a point in visiting anymore.
The only reason to go now is just to pop in and say you've been here before the eventually tear down the entire thing.
Although I do have to say romping around in the dark flooded basement was a bit of an adventure.
I'm quite proud of the basement photos. It was super dark in the basement and I didn't have a tripod on me. I basically just crouched and held my old dslr as steady as I could with my hands for each shot and they actually turned out pretty good.
Edit: fixed sideways photo
