Harry Potter Theme Park

I think it would be really cool to have a Harry Potter Theme Park. They could have a Hogwarts castle with all of the different areas seen in the books + movies complete with moving pictures on the walls (plasma monitors with ghostly images). You'd have to say the password, of course, to be able to get into the Griffendor common room :-) Voice recognition near the plasma monitor / moving portrait would match your spoken password with the actual password before letting you through.

Like the Disneyland Village area, they could have areas for Diagon Alley and Hogsmead where they would have "The 3 Broomsticks" where you could buy real Butterbeers (whatever that actually is...they'd have to make something up), The candy/joke shop, etc.

There are countless possibilites for this place which, with the huge popularity of Harry Potter would draw huge numbers of kids (and adults alike).

They could also have various magic incantations that when recognized by a wand (given or purchased in the park) would perform certain magical acts when done the right way and in the right place. This could be done by having some sort of transmitter in the wand along with a voice recognition module. When the sound of the "spell" is recognized, it will communicate (via 802.11b, bluetooth, etc.) with a nearby item that would perform some seemingly magical act.

Quidditch would be cool too, though I'm not sure how they'd do that...maybe it would be an amusement park ride. The whomping willow could be another ride.

I'd suggest the UK (England, Scotland) as the best location given the origin of the book, but due to it's huge popularity in the US, maybe somewhere near existing theme parks (California, Florida) would be better.
