Designed as a downtown convention hub, the upscale Sheraton Chicago Hotel & Towers, with its massive event facilities, caters to business travelers and big groups staying for weddings or conferences. The rooms are large and business-friendly, with desks and work space, but the Wi-Fi isn't free. On-site restaurants, bars, a cafe, indoor pool, and even a full service FedEx office make it possible to attend an event and never set foot outside the hotel. But other guests can get lost in the shuffle among the events and the endless blocks of reserved rooms. With 1,214 rooms over 34 floors, housekeeping struggles to keep up. Families or couples looking for the conveniences of a big chain hotel from which to explore Chicago have better options, such as the Hyatt Chicago Magnificent Mile or the Radisson Blu Aqua Hotel.
