This document summarizes Lan Yao's PhD research which examines differences in hospitality experiences across accommodation types. The research questions investigate how travelers describe their accommodation experiences and whether review contents and satisfaction ratings differ by accommodation type. A conceptual framework is presented that views hospitality as a human exchange on a spectrum from private to commercial settings. The methodology involves collecting and coding over 700 accommodation reviews from platforms like Airbnb, Couchsurfing and TripAdvisor to analyze differences in experiences based on factors like reciprocity, shared space, and platform features. Preliminary results indicate experiences differ based on payment, interaction level, accommodation type, and platform characteristics.
