Do you have any advice for potential travellers?
You will need warm clothing - obvious, but you may be sitting for three hours in a Zodiac with temperatures around freezing and in a chilling wind. Walks ashore are less of a problem.
The waterproof clothing and boots supplied on loan on the Ioffe were of good quality, there is no need to bring your own. Take some coloured clips to identify your boots amongst the 90 other pairs!
This is a very photogenic trip. Takes lots of memory, particularly if you intend shooting movie clips of whales and penguins.
The Ioffe rolls very little because it has effective stabilisers but if you are prone to seasickness it would be wise take medication for the Drake Passage.
