I agree the design of the Swan and Dolphin is more than the elements that make them up. They were two master planned hotels completed at the same time by the same design team. They were meant to be taken as a whole, but every whole is made up of parts. And often, to come up with some thing that works together in composition, you will look to the parts and ideas from the original design.
My example a couple of pages ago is a hotel in San Paulo. It has some elements of the Swan and Dolphin. It has a unique shape, it has circular windows, it is of a certain scale. And, it is a specific statement. Its not lazy design. Its not a corporate box. It is a unique design. But its a unique design that could stand in harmony with the original designs. Seeing it in context with the other two would work. That is what they should be aiming for here. (and I'm aware that hotel design wouldn't be done here, but there are ways to use what it shows us to develop a better hotel here)
I agree that this is just a lazy design.
And I know this won't be owned/developed by Disney, but I do believe they have some say in what can be built and/or could exercise some influence over the building, if they wanted to.
