How accessible is Antarctic expedition cruise tourism to visitors with specific needs?

Antarctica, known for its remoteness and harsh conditions, poses significant challenges for tourism. Despite the lack of conventional amenities and extreme climate, Antarctic tourism has grown, catering to diverse visitors, including those with specific needs. This paper examines how such an environment has been made accessible, contributing to the critique of medically oriented definitions of vulnerability and accessibility in tourism. It explores the experiences of passengers with dietary restrictions, limited mobility, plus-sized individuals, and able-bodied passengers facing unfamiliar activities. By studying Antarctic tourism for diverse populations, the research introduces the concept of "situational vulnerability," highlighting the fluid nature of vulnerability based on the visitor, their response to the environment, and the support they receive. The study also addresses the tension between inclusivity and safety in extreme environments. Data were collected during two Antarctic cruises aboard the Ocean Endeavour in January 2023, using interviews and observations of passengers and staff.
