Alan is right, look for the doors open or cracked after the dinner rush. Those are where you'll learn. Usually some long-timers will be in there telling stories or trying to figure out a mystery marble or something like that. Ask some questions and mostly just listen. There is always something to be learned, no matter how long you've collected. Definitely bring the bright light and extra batteries in your pocket. A small pocket notepad and pencil are useful to keep notes before you get off on another topic and forget. I was unsure about walking around in a hotel going to other people's rooms the first time I attended one but that apprehension disappeared immediately. What fun the shows are, we just had the Old South show in Valdosta and we had such a good time. Find a crowd with dinner plans and go with them, you will have a blast!
