Thanks for the replies. I will try to call, but am not holding my breath. They don't have the storage to keep all those pics forever (or even a couple of weeks). I really did get pretty good pictures (and hysterical video!)
RE: tips to get picked
1. be the older sister of a little boy whose only wish for his birthday was to get picked for jedi training (yes really, with no trying at all my DD got picked right off the bat, very first thing*sigh* we went to 6 more shows before DS got picked)
2. wear a Star Wars shirt of some kind. About 90% of the kids will be wearing Star Wars shirts, so maybe the odds are just stacked that way...
3. Get there 20 or more minutes early and stand at the front. They pick kids from all around the stage, so position isn't as important as being up front.
4. I saw 1 kid with a sign (something about pick me the force etc etc). That kid got picked. (I would have totally made a sign, if I had to go back to the Studios to get DS picked!)
5. They pick at least one little kid per show (3 or 4 year old). It is part of the show -- always showing them how to activate the light saber, telling them not to fall off the stage "no one likes a clumsy jedi"
6. most kids are in the 7 to 10 year old range. I think my son (turned 5 that day) was too old to be the young kid, but not as big as they like to see. I believe that by the 7th show, the jedi master took pity on me, and finally picked my son (last show of the day, last kid picked). It made our week!
7. They seemed to pick kids wearing their own jedi robes ("ah, I see we go to the same tailor") Coincidentally, they sell little jedi robes with Mickey ears on the hood - very cute, around $40 (IIRC) - we did not buy one of those
8. They pick about 16 kids. There will be at least 60 standing at the front waving. It is sad to not be picked.
FINALLY, and this is important -- the Photopass photographer that takes the pics of the kids on stage, takes pictures immediately before and after the Jedi Training Academy, right there by the stage, and they put DARTH VADER in the picture with you(you are in a light saber duel with him). IT IS VERY COOL. Some of my favorite Photopass pictures right there.
