Yes, now that I'm a planning student, I'm paying attention to these things! Navy Pier, the top tourist attraction in Illinois, is looking at doing $400 million of improvements. See the plans here.
I think the water park, huge Ferris Wheel, and floating parking structures are a little obnoxious, but I love the monorail is a great idea -- anything to help improve the transit getting to the Pier and getting around. Oh, and monorails are always cool.
Update: I forgot to mention that I heard about this on "Hello, Beautiful", a radio show about art, design, architecture and urban planning. Who knew?
