Sea World in Orlando, which in many ways is more like an aquarium than a theme park and takes its educational mission very seriously (honest!) has a nice compromise w/ moving walkways in its penguin exhibit. A people mover moves across the viewing area, but the more interested can move one level up (about 4 feet) and watch these altogether enchanting creature for as long as they like. Which can be quite a while-- they literally fly under water and it's fascinating tto watch. Ann Mintz Orlando Science Center
