The value of unsustainable hotel services to guests: Evidence from a discrete choice experiment
通过离散选择实验（785名参与者）评估不可持续酒店服务对客人的重要性，将服务分为三类，为酒店配置兼顾成本、设计和减排的服务包提供指导。
Hotels routinely provide room services beyond their core accommodation functions. Their value to guests remains uncertain. Some hotel services are environmentally unsustainable but not essential to the core function of accommodation. This study uses a discrete choice experiment ( n = 785) to determine how important such services are to tourists. We classify hotel services into essential but environmentally unsustainable ( air conditioning control ), non-essential and unsustainable services with negligible value ( single-use items ), and unsustainable services with differences in importance across market segments ( daily towel change , minibar , vacuum cleaning ). Findings provide guidance for configuring hotel service packages that can deliver a triple benefit: reduced cost for providers and potentially guests, an optimised room design, and lower emissions.
