The Ritz-Carlton Hotel Co will close its five-diamond property in Las Vegas this May, after the hotel struggled with a slide in demand and revenue. "It's nothing the hotel did. It's a simple lack of business and a decline in the tourism industry," said Ritz-Carlton spokeswoman Vivian Deuschl. The owners of the 348-room property, Village Hospitality LLC, an arm of Deutsche Bank, will stop funding the Ritz-Carlton Lake Las Vegas day-to-day operations on May 2.
