The Indy show website is saying the current run ends at the Discovery Science Center in April, so for this run anyway this will be it. Perhaps you're right and the Indy show will get another run in a few years that will come here, but I can only speak in terms of what is knowable. I'm frustrated that the youngest member of my family just turned 15 and wouldn't be remotely interested in doing the show the way you and your daughter did, that sounds way better.
Are you sure the Indy show won't hit LA some day? THe SW show hit OC last fall, so maybe in 3-5 years we'll have Indy... If I had gone to the show without my daughter, I would have gotten through it much faster- but I enjoyed spending extra time solving the puzzles with her and explaining all the movie stuff, plus I was an Anthropology/Archaeology major in college, so I had addition interest in the non-Indy aspects of the exhibit. I still say though that the crappy gift shop offerings were extremely disappointing since the SW show had such a phenomenal offering, but this isn't a movie year and Indy toys have no draw to kids anymore, so I guess mugs and t-shirts are ok.
Ha! Too funny. It's not worth missing though.
P.S. I was at Subway on Victory/Olive tonight and guess who shuffled in carrying a target bag, wearing a member's only jacket and a hilarious set of headphones atop a greasy mop of curly hair? Ding Ding Ding- it was the infamous "Headphones" guy. Sometimes I miss the hunt.
