Google's AI Mode Is Compressing the Hotel Research Session Down to One Exchange

Google’s AI Mode for hotel booking — live since August 2026 with ten launch partners including Booking.com, Hilton, IHG, Marriott, and Wyndham — is on track to eliminate the multi-visit research session that has historically favored hotels’ direct channels. Hospitality.today’s Markus Busch revisits Cornell professor Chris Anderson’s landmark 2009 and 2011 “billboard effect” studies, which found hotels listed on Expedia saw 9-26% higher direct reservations, and that across 1,720 InterContinental bookings, every single Expedia booking generated 3-9 additional direct bookings — a lift driven by travelers historically making around twelve visits and five minutes per page across comparison sites before booking. AI Mode compresses that entire session into one exchange: a guest describes a trip, gets one recommendation, and books, with no comparison shopping and no visit to the hotel’s own site.

Busch cites a June 2026 Tharro study of 695 unbranded searches through ChatGPT and Google AI Mode: hotel websites were cited as sources less than 10% of the time, with OTAs and review sites dominating instead. Confirmation emails compound the problem, carrying the booking platform’s name rather than the hotel’s — leaving guests unable to recall which property they stayed at, breaking the psychological “choice” mechanism loyalty programs depend on to drive repeat bookings.

Choice Hotels, one of the AI Mode launch partners, described the integration as letting travelers describe preferences conversationally and book through a “Continue on Google” flow while Choice remains merchant of record — Choice operates 7,500-plus hotels across 22 brands and roughly 650,000 rooms. That scale is exactly what makes Busch’s warning concrete: the billboard effect worked because comparison shopping routed attention back to a hotel’s own channels. AI Mode removes the comparison step entirely, and the brands agreeing to be found there are also the brands most exposed to losing the direct-booking premium that effect used to generate.
