The Remains of the Stay: Memory, Identity, and the Afterlife of the Guest
Edmondo Grassi approaches the post-stay phase as a sociologist rather than a technologist, and the perspective is unsettling. When a guest checks out, he argues, their stay does not end — it migrates into a data infrastructure that remembers with absolute precision what the guest themselves only vaguely recalls, raising a question the industry rarely asks: who has the right to hold that memory, and on whose behalf?
In the common imagination, a single gesture comes to mind when we picture checking out of a hotel: the guest sets the key on the counter, crosses the lobby one last time, and as the door closes behind them their story with the hotel comes to an end. For some years now that scene has been changing. The stay no longer ends at check-out; it merely changes form. The body that has left the room goes on living elsewhere, condensed into a profile, a trail of data, a prediction about what it will want next time.
I have spent many years studying how technology, and algorithms still more, reshape social life, its habits, its relational dynamics, the very tastes of a person, and few images render this as sharply. The guest leaves the building, yet their trace is etched into the managerial grammars of service, and for precisely this reason they have never been so present. What we call the post-stay is the threshold where it is decided who will keep the memory of that stay, and with what power to act.

The 2026 HOTEL Yearbook Technology Edition - AI Everywhere is fully geared towards AI and explores how hospitality technology is preparing for a decade of profound change. With a clear focus on practical impact rather than hype, this edition examines how intelligence is becoming embedded across the hotel technology stack and day-to-day workflows, reshaping operations, revenue, distribution, guest experience, and the back office.

It brings together a wide spectrum of contributors, including academics, startups, hotel brands, established solution providers, and industry insiders, offering evidence-led perspectives, real-world lessons, and actionable guidance on what hoteliers should prioritize now to stay competitive in an AI-driven future.
