Thanks for the question on room size. Fortunately I have both CTT and one OGR magazines issues and it took two to find some answers.
I do not have the size of the PAL Building BUT I have the room plot picture which is probably not to scale and shown below. It is from CTT Aug 1991 and the size of each layout from OGR Oct 1989, run 107.
Summer - 24ft x 16ft, Spring - 26ft x 8ft,
Fall - 27ft x 8ft, Winter - 22ft x 8ft
The room sizes are larger than the layouts and there are open areas for people to view the layouts in each room. But you can get the idea of how big the rooms are.
