I know some rides do tell you no videotaping (soarin' comes to mind), and I totally agree about using my digital camera to record what I need to.
I used to be totally anal about flash pictures and let it get me in a bad mood, but then I had a lighbulb moment when riding behind a flash-happy family on IASW...
These people had come from a great distance and might not ever come here again. I, on the other hand had seen it all before, and will see it all again. Probaly sooner than later. Instead of getting upset, i thought about how cool it must be to see it all for the first time, and want to remember this vacation. I totally got a warm fuzzy feeling, and ever since then Flash Photography doesn't phase me. Well, almost. it super annoys me when the myspace generation has to take a picture of themselves in a dark ride, blinding everyone else on the ride!
