Theme Park view for CR is described as "Tower Magic Kingdom Rooms offer views of the parking area and Magic Kingdom theme park."
Magic Kingdom view is only for Atrium Club/Concierge on the 12th floor (14th is also concierge but suites I believe) and is described as "Concierge Magic Kingdom View Rooms offer views of a parking area and Magic Kingdom theme park."
So they are pretty much the same- both are going to be in the tower and on the side facing the MK. MK View with concierge is more $$ of course and on a higher up floor.
