9 days, round-trip South America from Montevideo

About this cruise

This one leaves Montevideo on December 28, 2026 and spends 9 nights visiting Balneario Camboriu, Ilha Grande, Rio de Janeiro, Ilhabela and Buenos Aires at a pace where every day has something going on but there's always time to just sit and watch the water too. There's a stretch of back-to-back port days, so those days are busy, but the sea days around them give you time to recharge. Tango, rainforest, Patagonian ice. South America covers a lot of ground. Most ports give you about 9 hours, so you can do more than just tick off the main sights. As for the ship itself, Costa Serena: 3,014 guests, 13 decks. Entertainment, dining, and enough space that it never feels cramped. The timing adds to it: swapping cold weather for sunshine and sea air is the whole pitch for a winter cruise. 9 nights of not thinking about anything except where to eat next. That's the pitch.
