We got advertisment with a gym on board. There is none.
The itenirary of the ship is without competition and very interesting. Going both direction makes no sense (increased proximity to land on cape horn, we did both direction, landing was possible only once; from Puntas Arenas down to Ushuaia is better - you see the alley of the glaciers by daylight).
The vessel is new, every cabin is more or less the same with a big window and proper equipped.
There is 1 (!) public toilet on board. No restrooms close to restaurant, no restrooms at the bar. You have to run some floors down or up to your room. Plan your service stops carefully.
Ship is all inclusive. Drink selection limited. Coffee ok. No Wifi (!?).
Zodiacs need to circle to get all the passengers on land.
Crew is very varying. Some Zodiac drivers and guides are super professional and with huge knowledge, others are who knows where from. Same for the waiters, some cannot basic english (and the boat is mostly frequented by Australian, US, Canadian, UK, German).
Activities are split in moderate, challenging and very challenging. Very challenging is still not sportive (target group wealthy 60+).
I would not book again for this price.
