The Rezidor group is continuing to develop the Radisson Blu brand in the United States with its third establishment there. The Radisson Blu Warwick in Philadelphia joins the Radisson Blu Aqua Hotel in Chicago and the Radisson Blu Mall of America in Washington D.C.According to Javier Rosenberg, Radisson's COO for the Americas, the development in Philadelphia is essential to the Brand's U.S. expansion, noting Philadelphia as "a key East Coast gateway city and an international business and cultural center".A $20 million renovation project saw The Warwick hotel become a Radisson Blu establishment, after "more than 86 years as a symbol of distinctive hospitality," in Rosenberg's words. The renovations included a redesign of all 301 guestrooms and corridors, a new Business Class floor with a private lounge, and the hotel's grand lobby to reflect the contemporary Radisson Blu style.
