This would be bad for operators and tourists. It would also be bad for Antarctica — and the planet.
The answer may lie in economics.
Future visitor trends

Antarctic tourism is managed by an international set of agreements, together known as the Antarctic Treaty System, as well as the International Association of Antarctica Tour Operators (IAATO).
The treaty system is notoriously slow-moving and riven by geopolitics, and IAATO does not have the power to cap visitor numbers.
Pressure on a fragile continent
Each cruise ship traveller to Antarctica typically produces between 3.2 and 4.1 tonnes of carbon, not including travel to the port of departure. This is similar to the carbon emissions an average person produces in a year.

Global warming caused by carbon emissions is damaging Antarctica. In the Peninsula region, glaciers and ice shelves are retreating and sea ice is shrinking, affecting wildlife and vegetation.
IAATO has pledged to halve emissions by 2050 — a positive step, but far short of the net-zero targets set by the International Maritime Organization.
Can economics protect Antarctica?
Research shows these tools could also prevent Antarctic tourist numbers from getting out of control.
Any cap on tourist numbers in Antarctica and rules for trading must be based on evidence about what the environment can handle.
This could be backed by robust monitoring and enforcement to avoid greenwashing.
