Sheraton Hotels is investing more than $100 million to upgrade 120 Club Lounges around the world, including at properties such as the Sheraton Waikiki in Hawaii, Sheraton Denver, Sheraton Centre Toronto, Sheraton Hong Kong, Sheraton Buenos Aires in Argentina and Sheraton Edinburgh in Scotland. The enhancements are the final piece of the brand's $6 billion revitalization. In addition, all Sheraton Club Lounges now are open every day to accommodate demand. The lounges are rated by Starwood Preferred Guest members as one of the top two benefits of staying at a Sheraton; SPG members account for half of all Sheraton hotel bookings. Club amenities include complimentary breakfast, afternoon hors d'oeuvres, beverage service, flat-screen TVs, free Wi-Fi, a selection of daily newspapers and more.
