There are some destinations where cruise ship size really matters, none more than the Panama Canal. The 2,000-passenger Coral Princess was built to fit the specific criteria needed to navigate the canal’s original locks and (along with her almost-identical sister, Island Princess) spends much of the year traversing the canal from the Pacific to the Atlantic and back, and also taking guests on a global adventure during Princess Cruises’ world cruises. The ship’s small size means the onboard activities are more laid-back than on megaships, with sitting back and enjoying the view a preferred way to pass the time.
