If you are using a video camera, and especially at Little Mermaid, avoid using the "Nightshot" feature if your camera has it. That sends out an infrared light and will make anything hidden appear on your camera, and possibly other peoples. When I first got my camera with Nightshot, we used it in Little Mermaid, and I turned on the Nightshot just to see what would happen, and all the people in black moving the characters around were lit up like daylight. It was kind of eerie. Also, anyplace where Disney has their infrared cameras set up in rides to monitor people, you can see a flash on the tape of the light blinking.
