I can't help but think that the people who are so adament about no lights whatsoever, if the ride was totally dark, would find somehing else to complain about. A child being to loud, the boat rocking too much, whatever. This is Disney World. Thousands of people a day, and most of them will not act and think exactly like you. There is no ride rule book that states lights are not allowed. So if a child needs a small light for comfort, so be it. As the adult you can then approach the ride knowing there may be lights and decide if you wish to ride it or not.
