Yes, you can get to know folks in the waiting room, and others' experiences are always helpful, especially since they are using the same crew. You might get insight into whether there is a better schedule or not (although it sounds like you are in good shape in that area!) I enjoyed having the opportunity to encourage one or two guys that came after me. Especially since we have gathered up a lot of info by the time we get to SRT, we can be a good resource to others in there.
I hope all goes uneventfully for you. I was pretty fortunate - only real side effect was fatigue.
Best regards, Jeff
