LONDON -- A new concept in cruising the Caribbean has arrived in the form of a ship called easyCruiseOne. The ship's flexible weeklong itineraries offer a different port of call each day. Passengers may join or leave the cruise from any stop, as long as they stay on board for at least two nights and no longer than 14 nights. But there are no free buffets, and you have to pay extra if you want your bed made. The schedule starts with weekend ports of call in Barbados, followed by stops in St. Vincent on Mondays, Martinique on Tuesdays, the Grenadines on Wednesdays, Grenada on Thursdays, and St. Lucia on Fridays. The ship docks around 10 a.m. each day; passengers can enjoy the island for the day and evening, but they must return to the ship by midnight. For those who wish to remain on board rather than explore the islands, a la carte food is available. Similarly, maid service is optional; if you want your room cleaned, housekeeping is $10 a day. The six-deck ship, which carries 170 passengers, also has a sports bar with evening DJ, a six-person hot tub and a gym. Rates for a standard cabin range from $30-$72 per person per night, based on two people sharing a room. For menus, pricing and other details, go to http://www.easyCruise.com or contact a travel agent. The easyCruise company first offered its unusual format last spring and summer along the French and Italian Riviera, with ports of call in Nice, Cannes, St. Tropez, Monaco, Genoa, Imperia and Portofino. The ship has relocated to the Caribbean for the winter. The company reports that more than half of the passengers booking easyCruise Caribbean trips so far this season are American, and the average age of passengers is mid-to-late 30s. In contrast, the median age of passengers aboard traditional cruises is 47, according to statistics from the Cruise Lines International Association, which represents 19 North American cruise companies.
