The Hospitality Sales and Marketing Association International (HSMAI) has introduced the Ancillary Revenue Strategy Playbook, offering hotels a roadmap to diversify income beyond room sales. With costs rising and traveller expectations shifting, the guide highlights opportunities in food and beverage, spa services, day-use rooms, and underutilised spaces. Including vendor resources, case studies, and performance metrics, it equips hoteliers with practical strategies to boost profitability, enhance guest experiences, and build resilience in a competitive global market.
