Raphael, the location of Cinderella Castle plaza is not really used at Walt Disney World. The area that you are describing is the Cinderella Castle forecourt. Hence, we use the terms of forecourt for the front area and courtyard for the back area of the Castle.
I truly appreciate the information but I'm simply making reference to the Central Plaza as seen [here](http://disneyparks.disney.go.com/blog/2015/05/first-look-cinderella-castle-adds-regal-turrets-at-magic-kingdom-park/) through an official Disney channel and making it understandable to the passing reader who may not have extensive knowledge of the park's most intricate details. I did not capitalize the plaza as it isn't the proper name but just referenced its proximity to Cinderella Castle. I also was referencing a post that included information about areas that extend out past the Castle and into the "hub."
Yes, then the areas that were covered would be mentioned as two distinct areas: the Cinderella Castle forecourt and the Central Plaza area commonly know as the "Hub". I have never heard the area called Cinderella Castle plaza, but you are more than welcome to use it as you please. It is your blog. I believe you merged the two areas together as one which I have never seen it described that way. Even the official Disney Channel that you referenced states that one area as the Central Plaza.
