Disney's America 3.0?
themeparkinsider.com/flume/200906/1248Disney has purchased land in Washington D.C. to build a major resort/water park/themed area....basically, the head designer said that since Disney failed twice to build an American History-themed park, this was their attempt to "do it" right. The designs showed a very, very large historical-type resort hotel with an adjacent water part. They said, however, this plan was in the very early stages.
