So, it really depends on the attitude of the current president as to how much he wants to invest in the park he's in charge of. It CAN be beneficial if he has the right attitude.
Ever since Pressler, the real power and control of the Parks has rested in Burbank, and it still does today. The DL president still has to answer to Meg in Florida, and Tom and Bob in Burbank, and the board and stockholders.
Michael can't just decide to build a new attraction cause he's just that swell a guy. It doesn't work that way. And no matter how nice he is, if Burbank says to cut spending, he will.
