That pic brings back memories Ben.
I used to work in the central hotel about 25 years ago. I was part of the maintenance team and one of my tasks on a Monday morning was checking emergency lights and relamping any that were out. I hated the walk along the 6th and 7th floors, used to really spook me out.
When was that pic taken, can’t believe rooms still have stuff left in them. We had a fire on the 6th floor and all the rooms were supposed to be cleared out, hadn’t happened by the time I left though.
edit: Just had a look at your site. I worked there when that bar was built in your last pick, that was all hand built and cost a fortune.
Don’t know if you managed to get up the clock tower but there’s some good exploring there, the old carpenters room and the water tank are both worth a look. Accessed from the 5th floor.
