Disney accused of squeezing theme park customers- PublishedDisney is facing criticism from a high-profile investor that is unusual in the business world: that it is squeezing money out of its theme park customers.The firm's reliance on raising ticket prices and other charges to drive growth is "unsustainable", says Trian Partners boss Nelson Peltz."However, we suspect it is short-term thinking that puts the brand value and long-term health of the business at risk."Mr Peltz is an activist investor known for battles with big companies such as fast food chain Wendy's and Procter & Gamble, maker of brands such as Pampers and Vick's.He says the firm overpaid to buy the bulk of Rupert Murdoch's Fox empire and granted "over-the-top" compensation packages to chief executive Bob Iger, who was recently reinstalled as chief executive."
