20 Night Cruise from Barcelona

About this cruise

If you've got 20 nights to work with, this sailing from Barcelona on November 3, 2026 through Málaga, Cádiz and Lisbon, with additional stops along the South America is genuinely one of the better ways to spend them. The trip wraps in Santos, so you won't retrace your steps. The 10 sea days in between leave time for the pool, the spa, or whatever else you feel like doing between ports. The South America route takes in Spain, Portugal, Cape Verde and Brazil, 4 countries, and the differences show up in the food, the architecture, and the mood. Keep an eye out for Cádiz: Europe's oldest city, still dancing flamenco. 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. There are enough performances, events, and social mixers on a cruise this length that you couldn't do them all if you tried. And that's a good problem. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. If you can, add a night in Barcelona before boarding. It's a good city to wander. The autumn timing is underrated too. Good weather, calmer seas, and a more relaxed ship. That's 20 nights well spent.
