I remember that as I took pics there. I really think its the phone camera issue more than anything else.
Putting my flame repelent on here. But if your not using a big white lens, have the back lcd turned off, no flash, have any confermation beeps turned off and stay in your seat you might be able to sneek a few shots off.
All cameras have their little annoyances. Camera phones have the LCD blinding those sitting behind. P/S have the little focus assist light and maybe a flash or two, and SLRs have that huge CERCHUNK every time you press the shutter. All can be annoying to someone just wanting to watch the show.
