There are advantages to public and private ownership, says Hilton Worldwide President and CEO Christopher Nassetta, who was president and CEO of Host Hotels & Resorts. The access to capital as a public REIT is clearly a plus. But being a private company allowed Hilton Worldwide to integrate its various operations and transform itself into a global business. "When Blackstone bought it, it was a great company but put together through mergers and acquisitions," he said. As the business moves to a different place, "we will consider exit options, including an IPO."
