6. I researched all four chains at Boston for my family vacation: Marriott (Marriott near Boston Harbor, Residence Inn, Courtyard at Tufts Medical Center, etc), Starwood (Sheraton, Westin, W, Four Point at the airport, etc), Hilton (Hilton at financial district, DoubleTree at Tufts Medical center, embassy Suite, 3 of the Hampton Inns, etc), and Hyatt (at the airport).
