Chris, that's the exact same thing that happened to me. I kept meaning to book a slot in one of the tour groups, but I had so much to do, I just never got around to it and then it was too late. Next reno

Cormier, yes, there is no usable space in the Tower portion beyond the 7th floor. 8th floor and up is unusable due to fire regulations. Back when the fire code wasn't so strict there were offices in the tower. During World War II, the guy (can't remember his name right now) in charge of media censorship had his office up there. I don't know when they stopped using it.
