How Has PortMiami Contributed to the Return of the Cruise Industry?. Miami, home to PortMiami, one of the busiest cruise ports in the world, is experiencing a significant resurgence in its cruise industry. After a challenging period for global travel, cruise operations are returning in full force, and PortMiami has played a vital role in this revival. As the cruise industry bounces back, the ripple effects are being felt throughout the local economy, particularly in Miami’s hospitality sector. With passengers arriving early or extending their stays after cruises, demand for hotels, restaurants, and entertainment has surged, providing a boost to businesses in the city.
