Ah, but then how is the really pertinent example of a helicopter tour different from a rollercoaster? Transportation or not, you still want the helicopter to use the utmost level of safety. Thrill ride or not, you certainly want the rollercoaster to use the utmost care for your personal safety, do you not?
Is a water taxi on a "real" lake that different from the water taxis that cross the World Showcase Lagoon at Epcot? It's a body of water bigger than all of Disneyland, but it's within a theme park and is man-made. People have drowned in the four-foot depths of the Rivers of America; do you want the Epcot water taxi's subject to a lesser safety standards because they are operating on "man-made water" inside a theme park?
