Do you have any advice for potential travellers?
Wish I'd taken a hat with ear flaps and an inbetween coat. Sometimes my triple goose down parka was a bit too warm (it can get quite warm in the sun when worn together with the waterproof outer gear) and my thin jacket (for the BA sun) was not warm enough for Ushuaia. The thin inner finger gloves are very useful when taking photos. Thermals are a must. Layers of thin polo necks best. Tee shirt OK in ship but need warm coat for deck. No special shoes/boots required. Rent wellington boots, waterproof jacket and trousers on ship. Travel light. Take lots of film and extra batteries.
Worst airport (BA to Ushuaia) experience I've ever had (and I've done a lot of travelling). Long queues. Very few of the staff speak English. Chaos. So nearly missed flight. Met quite a few other people who had a similar experience. Get to the airport early. Coming back was better. Nice little airport at Ushuaia.
