We are booked on this cruise, it is stopping at Roatan, Belize, Cozumel, Grand Cayman and Key West. It is not a "special" cruise as far as I know. We picked it because we loved Millie and Constellation and Summit is their sister ship. Also because it is a great itinerary, we have spent weeks at each of these ports on prior vacations. I too have thought it was odd that it only sails to the Western Caribbean for only one week.
