If you're looking for a tropical adventure in the Western Caribbean, hop aboard the Sky Princess. For eight nights and seven days, this mega-cruiser whisks its 3,500 guests to Cozumel, Belize City, Roatán, and Costa Maya, visiting white-sand beaches, underground rivers, ancient Mayan ruins, and the second-largest barrier reef on the planet. Meanwhile onboard, Captain Tuvo and his crew are hard at work-above and below the waterline-handling twisting channels, an unnerving false alarm, a malfunction in the tanks that keep the ship level, and more.
