While we do not always like the way a particular law works, that doesn't mean we can just ignore that law. Disney got a good deal when they purchased this land, knowing the terms of the purchase. They should remain grandfathered in to these terms. They are not the only business to be exempt from land use laws.
No, Disney World should not be exempt from all Florida land use laws. In the best interest of lawmakers and residents, no company should be exempt from land use laws. How will this company be held accountable if it is able to use it's land in whatever way it chooses?
Special districts that grant certain exemptions to businesses are not fair to the companies that don't get to enjoy those same benefits. Of course Florida wants to accommodate Disney World; however, Disney World should not necessarily get special treatment that other Florida businesses can't get. Treat all businesses the same.
Disney could possibly get some breaks, but I don't think it should be completely exempt from all Florida land use laws. That doesn't make sense and could possible hurt Florida in the long run. I get that Disney is a huge producer of tourism and probably pumps some of that revenue back into the state, but allowing it to be exempt from all land use laws just gives it carte blanche to do whatever it wants regardless of environmental impact ect.
