Raise your hand if this cruise sounds familiar: Nassau, St. Thomas, St. Maarten. How about Ocho Rios, Grand Cayman, Cozumel? We thought so. Like you, today’s cruise lines are looking for new frontiers. Problem is, big boats require big ports, and not many cash-strapped island governments can afford to build them. Enter cruising’s newest trend: ports developed (or redeveloped) by cruise lines. Starting with Carnival’s renovation of Grand Turk in 2006, the big players have financed port projects in Falmouth, Jamaica, and Roatan, Honduras, using them to replace old standbys or at least diversify itineraries. Despite the hefty price tags, the new ports are a win-win: Passengers get a fresh stamp in their passports, and cruise lines get a novel destination tailor-made to their desires. And because the ports are purpose-built, the lines can design shore excursions, shopping and dining around their cruisers’ preferences. So if you’re seeking new ports for your next cruise, chances are you’ll find them (see below). If not, cruise lines are building them. All you have to do is come.
