Macmyday - Having spent three weeks in Antarctica and South Georgia this year, I would say there are significant drawbacks to taking a cabin on a small yacht like Legend. There are advantages as well - being so small it can access tiny coves and inlets and it can give you a fairly immersive experience within a short space of time.

However, I think the drawbacks are more in number. The main thing here is the weather and it's a fair chance that a flight from Punta Arenas across the Drake Passage might never take off. This flight path is usually reserved for med-evacs. Weather can close in, seas can become seriously heavy and a little yacht like Legend will feel like a cork in a waterfall. I've been on an expedition ship with 50 cabins in the heaving South Atlantic and it was not pleasant at all. Also, having looked at the Legend on YouTube and elsewhere I can see that it lacks deck space for comfortable viewing of the scenery and the wildlife. Outside areas look very compromised. Food will be very limited. Dining will be communal. If the weather is bad and you can't land for three or four days this yacht will seem incredibly claustrophobic and who knows who you will be sharing it with. Personally I don't think it's worth the risk.

I think if you were in the Galapagos or wanted to see seriously remote Pacific islands like Pitcairn or Tokelau then the Legend might be a good choice.

My trip to Antarctica and South Georgia was on Seabourn Quest - I thought it offered a thoroughly satisfying sightseeing experience combined with vast amounts of space and dining options. The speed and stability of the ship was impressive. If you want to splash out they have suites as big as the best luxury hotels. BTW, we had Steve Wozniak on our sailing.
