There are lighthouses, boutiques and breweries to enjoy as well.
MSU's beautiful campus is within a 5 minute drive of the Courtyard Marriott and has great restaurants and bars on Grand River Ave.
The Tigers are in town with home games against the Texans and Nationals June 25-30 for those baseball enthusiasts who'd enjoy a game at Comerica Park in downtown Detroit.
