Very nice shot of Fantasmic, roxrox!
One thing that just popped into my head that I've noticed while in dark attractions, is that the "auto focus assist light" can be almost as distracting as a flash. Did you make sure you had that turned off? Just curious. I would think that the assist light on some of today's dSLRs would be distracting enough, especially if you were sitting close, to make the CM make an announcement.
Sorry for going off topic guys, but this is important stuff!
