The hospitality industry faces a persistent challenge in the form of booking cancellations, which impact revenue, distribution costs, and operational efficiency. The INN Hotels Group, a prominent chain of hotels in Portugal, has partnered with our data-driven firm to address the growing issue of booking cancellations. In response, we embarked on a comprehensive data analysis and predictive modeling project to identify influential factors, develop a cancellation prediction model, and formulate profitable policies to mitigate cancellations.
