Unlike most people on this trip my husband had to drag me kicking and screaming to Antarctica! I am so glad he did. This has been the most amazing time. Everything surpassed my expectations. Cabins were much bigger than I had thought and the food was wonderful-thankyou Tracie and her fabulous staff Service both meals/bar and cabin was wonderful too. But more importantly the excursions, experiences and JUST EVERYTHING was mind blowingly fabulous. We have made many beautiful friends from all over the world which i also did not expect Thank you thankyou thankyou Shane and all the team from out tour operator <3

We had a fantastic experience working with Florencia and Mery from the team! From the very beginning, they were true partners in helping us craft an itinerary that felt personalized and well-balanced. Communication throughout the planning process (and during the trip itself) was also excellent. They were always responsive and proactive, and we especially appreciated the valuable updates they provided while we were traveling. For example, when a transportation strike unexpectedly happened during our trip, they stepped in to help us navigate the situation and adjust our plans smoothly. Would absolutely recommend them to anyone looking for thoughtful, well-supported travel planning!

The trip was really good with lots of standout places and experiences. Our trip manager was brilliant. He was friendly and knowledgeable and made everything easy. Some of the accommodation wasn’t the best (poor showers, uncomfortable beds, no safety lock box, no elevator) but for the most part acceptable.
