There will be a rather large area we will call home in the autograph hall called volunteer headquarters. There will be room in this area for you to stash whatever it is you absolutely must bring with you to your shift. But, folks, there will be at least 120 of you working at one time and that could result in lost stuff. So I would advise that you bring only yourselves to the hall when you report for duty. Someone like myself or other trusted beings will always be at this booth to look after whatever is back there, but we can't be responsible for lost vinyl-caped Jawas and such.
