Hotels Hyatt Regency Kansas City to become a Sheraton By Danny King / July 20, 2011 Share 1 -- The Hyatt Regency Kansas City will be reflagged as a Sheraton on Jan. 1, following a $13 million renovation of the 733-room hotel. The hotel has been a Hyatt Regency since it opened in 1980. Thirty years ago this week, the hotel was the site of a structural disaster — a walkway collapse that killed 114 people and injured 216. Following the renovation, the Sheraton Crown Center will have 95,000 square feet of meeting space, an indoor-outdoor pool and a new gym, said Starwood Hotels & Resorts, owner of the Sheraton brand. A sister property, the Westin Crown Center, is already located at the 80-acre Crown Center entertainment district in the southern part of Kansas City, Mo.
