The 'See the World -- Winchester' programme was funded by the UK Turing scheme in 2021-2022 and aimed to broaden the horizons of historically marginalised students who may not otherwise have had access to extracurricular opportunities such as international travel. The purpose of this article is twofold. Firstly, the authors reflect on the successes, failures and challenges involved with running internationalisation activities during a time of travel disruption. Secondly, this article presents findings from a small-scale evaluation that sought to measure the impact of short-term mobility with historically marginalised or under-represented students. The paper is useful for institutions looking to run international mobilities with students during a period of travel disruption using the COVID-19 pandemic as a case study. In addition, the findings highlight the experiences and benefits to students participating in short mobilities, which include, a cultural experience, opportunity for personal growth and development, enhanced employability, and ultimately, broader horizons.
