We just finished our Antarctica trip on Atlas World Navigator. Based on my experience I would never go on another Atlas cruise or recommend it to anyone. Here’s why: The ship is beautiful and room attendant and restaurant staff are wonderful but the cruise was run wrong every step of the way: 1) we arrived at Orlando airport on Saturday ( flights booked by Atlas). We were told someone would meet us at the baggage claim area but no one was there. I called the Atlas phone number and was told that we should find our own way to the hotel. The line is closed at 5pm so by pure luck I called at 4:50 and was able to reach someone; 2) the cruise before us was delayed due to weather so we were stuck in Ushuaia from 8am till the next day. Instead of putting us in a day room they drove us around on buses until the normal check in time. At this point most of the passengers haven’t hit the pillow for over 36 hours. 3) The president said for the lost day we would get half day back at the beginning of our cruise and half day at the end. On the return ship was docked at 7am as originally scheduled so we never got the half day back. 4) the itinerary said we would make 9 landings but we only made 4. I understand that’s weather dependent but they never attempted to find alternatives. Moreover, one of the missed landings at the 10am announcement we were told to get ready for landing at 10:45 and the next announcement came at 2pm and saying we couldn’t go ashore due to weather. We later learned that from 10am to 2pm Henry, the excursion Director, was ashore getting married himself. So while it was safe for him and wedding party to spend 4 hours ashore all other passengers were waiting in the rooms to get updates. 5) a fellow passenger took a shower on the first day and the whole bathroom was flooded with an inch of water. Instead of fixing the issue right away they took 48 hours to solve it. It was not until Day 3 that they got moved to a different cabin. 5) they ran a photo contest but the winners only got their prizes after multiple demands. 6) Disembark was at 9am and the 12 hour charter flight back to Orlando was not until 11pm. Instead getting us a day room they just put us in a hotel meeting room. By the time we got to Orlando we haven’t slept for 36 hours. If you are from the west coast like us add another 12 hours because they booked on a flight home that left us waiting at the airport for 7 hours.
