20 Night Cruise from Genoa

About this cruise

You come back from a trip like this actually rested, not just "I went on vacation" rested. 20 nights from Genoa on November 2, 2026, visiting Barcelona, Málaga and Cádiz, with additional stops along the Western Mediterranean. You get off in Rio de Janeiro, which is a good excuse to tack on a few days on land. The mix of 10 days ashore and 10 at sea means you won't feel like you need a holiday from your holiday. The Western Mediterranean route takes in Spain, Portugal, Cape Verde and Brazil, 4 countries, and the differences show up in the food, the architecture, and the mood. Don't rush through Lisbon, which is known as Seven hills of fado, pastéis, and golden light. Roughly 8 hours ashore per stop. No need to rush. Costa Diadema carries up to 3,724 guests over 14 decks. Multiple pools, a theatre, and more restaurants than you'll get through. With more nights comes more time for the ship's rhythm to kick in: morning coffee in the same spot, evening shows, late-night conversations on deck. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. If you can, add a night in Genoa before boarding. It's a good city to wander. And November is a good call. Still warm, less crowded, and usually cheaper too. All told, 10 ports across 20 nights covers a lot.
