Gaucho & Samba Rhythms – Buenos Aires & Montevideo

About this cruise

You board in Itajai on December 19, 2026 for 7 nights visiting Santos, Buenos Aires and Montevideo, and you come back from this kind of trip wondering why you don't do it more often. The 3 sea days in between leave time for the pool, the spa, or whatever else you feel like doing between ports. Crossing 3 borders through the South America: Brazil, Argentina and Uruguay. You'll notice the culture shift at every stop. Montevideo alone is worth the trip, Mate-sipping elegance on the Río de la Plata. Around 9 hours per port on average, which is generous enough to go beyond the obvious. At 132,500 gross tons, Costa Diadema is big enough that you can find a quiet corner or a crowd, depending on your mood. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. A December sailing is basically an excuse to chase the sun for a week or two. Worth booking. That's the short version.
