There's no way to be really sure. Both the big draw name narrators are already booked...Whoopi and NPH. I doubt you'll get anyone more popular than those two! As far as which show to get in line for, Robo is correct...get in line, two hours prior to the start of the first show. Then wait. I've actually seen people in the standby line at noon!!! They had one of those folding chair/cane thingies and a book!! There is no way I'm spending that much time waiting in a line to see anyone!!! You should be able to stand outside the theatre and watch...worst case scenario is you're four rows of people back, but you'll still hear it. Or, go over to the Liberty Inn and grab some food and sit and eat, while listening to the show. No, you really can't see anything, but the sound is good!
