Sailing Itinerary

Note: Cruise itineraries are subject to change. Please verify ports and times directly with the cruise line.

Day 1Port of Call Fort LauderdaleDeparture 5:00pm

Overview

Ft Lauderdale is a city of islands held together by an intricate web of canals, rivers, bays and waterways hundreds of miles long. Needless to say, boating is a favorite city pastime, whether zooming along on a speedboat, enjoying a fishing charter, or cruising the coastline by yacht. Beautiful homes of every size and style make up the bulk of this primarily residential area. By the beach, a leisurly stroll can be taken along the new landscaping wavewall design of the beachfront promenade. But this city is anything but sedate. Once a spring break hot spot, the town still has an energetic and colorful nightlife. Nearby, charming Laudrdale-By-the-Sea is home to one of the only living coral reefs in the US accesible from shore. Las Olas Boulevard, a shoppers paradise, is the chic new shopping and trendy dining area of downtown. If sports are more your inclination, dozens of golf courses and hundreds of public parks allow you to absorb the great Florida outdoors. Cultural arts are also popular. Water taxis bring theater-goers from throughout the city to the Performing Arts Center on the water.

Day 2Port of Call Perfect Day Coco Cay Arrival 7:00amDeparture 5:00pm

Overview

With one-of-a-kind ways to thrill and chill, all in the same day. Like conquering the tallest waterslide in North America, and snapping a shot from 450 feet up in a helium balloon. A drink at the swim-up bar in the Bahamas’ largest freshwater pool. Or a taste of Bora Bora in the only private overwater cabanas in the Bahamas. This is Perfect Day at CocoCay. South Beach, Coco Beach Club and the overwater cabanas will open in December 2019.

Day 3 Cruising
Day 4Port of Call Falmouth/Jamaica Arrival 8:00amDeparture 6:30pm

Overview

Falmouth is the chief town and capital of the parish of Trelawny in Jamaica. It is situated on Jamaica's north coast 18 miles east of Montego Bay. It is noted for being one of the Caribbean’s best-preserved Georgian towns. Founded by Thomas Reid in 1769, Falmouth flourished as a market centre and port for forty years at a time when Jamaica was the world's leading sugar producer[citation needed]. It was named after Falmouth, Cornwall in England, the birthplace of Sir William Trelawny the Governor of Jamaica who was instrumental in its establishment. The town was meticulously planned from the start, with wide streets in a regular grid, adequate water supply, and public buildings. It even had piped water before New York City.

Day 5Port of Call Cayman/George Town Arrival 7:00amDeparture 5:00pm

Overview

Miles of powdery white beaches above clear blue water and one of the richest marine environments make Grand Cayman one of the Caribbean’s finest vacation destinations (and a world class scuba diving destination). As a British Crown Colony, Grand Cayman enjoys all of the benefits of sophisticated government, touting one of the strongest economies in the Caribbean (with over 600 banks) while still allowing visitors to enjoy duty free shopping in Georgetown for jewelry, art, local crafts, and unique souvenirs like treasure coins from a sunken Spanish galleon circa the “Pirates of the Caribbean” era.
