A water taxi would also be an oustanding idea. I still wonder what is up with the water around the Tree of Life.
Its not attractive, Look kids, stagnate, muddy water!
It does not provide any transportation benefit (Other than an occasional character boat), and in fact the limited bridges increase park congestion.
It does not provides entertainment value, nor a unique wildlife viewing experience. Now if it were a giant clear blue reef
The water used to have a boat ride on it. They closed it down a few years ago. There were two stops on the ride, one where Pooh and Friends have photos now and one almost across from the Flights of Wonder show.
