Seven Seas Grandeur: 10-Night Caribbean - Eastern

Miami cruise port, officially called PortMiami, is the busiest cruise port in the world by passenger volume. Millions of people pass through here every year, and nearly every major cruise line uses it as a home port.

San Juan cruise port is one of the busiest in the Caribbean and one of the few that doubles as both a major embarkation point and a popular port of call. The port sits in Old San Juan, the historic colonial core of Puerto Rico's capital, founded by Spanish colonists in 1521.

St. Maarten cruise port is one of the busiest in the Caribbean, with ships docking at the A.C.

Most cruise passengers arriving at La Romana are headed somewhere else - Casa de Campo, the Caribbean's most exclusive resort complex, or Altos de Chavon, a replica Mediterranean village perched on a cliff above the Chavon River. Cruise ships dock at the Central Romana port, about a 10-minute drive from the Casa de Campo resort area.

Nassau cruise port is one of the most visited in the Caribbean, with up to six ships docking at Prince George Wharf on a busy day. The port sits directly on Bay Street in downtown Nassau, so you're essentially stepping off the ship and into the city.
