In this July 13, 2011 photo, people walk through the recently opened public dock and terminal in Detroit. Cruise ships are expected to call at Michigan ports 23 times next year, more than tripling the seven visits paid in 2011. A leading attraction will be the public dock and terminal that opened recently in Detroit. But the huge vessels also will stop at a dozen other places around the state, with routes extending all the way to Houghton in the far western Upper Peninsula.
