We just returned from an absolutely amazing trip to Antarctica with the World Traveller. Beautiful ship with a wonderful crew and great expedition team. The crew were super friendly and helpful and the service was top-notch. The expedition team were a diverse and passionate group who provided great educational content and guided us safely (for us and for the sites & wildlife) through 9 memorable excursions. The food was consistently very good and there was a good variety of options at each meal with plenty of tasty snacks between.
The cabins were clean and comfortable with plenty of storage for two people and everything secured well for crossing the Drake Passage. There was some noise (creaking and such) during rough seas but honestly, we weren't sleeping particularly well anyway on the crossing. The bathroom was a very good size with a large shower and plenty of hot water (heated by the heat produced by the engines).
We would definitely travel with Atlas again and look forward to seeing what new ports they add. Great experience.
