So to sum up the story A80 linked about someone being turned away from a voyage to the ice wall:
A reality TV personality took an unpermitted and uninsured trip to Antarctica. They Made it to McMurdo Bay. TV star and other crew members were exploring on land, using ATVs when the 3 remaining crew aboard their ship set off an emergency alert. The ship sank and the three crew are presumed dead after a search led by multiple nations.
Fast forward a little and TV personality wants to go back to find his boat. He files no paperwork in any country, and has passengers on board who dont have passports. He makes it back to McMurdo Bay, searches for his previous ship, gives up then heads towards Argentina/Chile because they are already in trouble in NZ, their port of origin. They get detained and fined in Chile for a myriad of minor offenses.
TL;DR. Guy who got 'turned away' from going to the ice wall actually went there twice, and ventured beyond it in his first visit. Didnt get 'turned away' until he'd already left Antarctica and returned to south America.
