Hotels Are Missing 1 in 5 Guests and It’s Costing Them More Than They Think
By Felix Dreizehnter, Head of Product at Ireckonu
For decades, the hotel industry has measured guest value solely based on room stays. If a guest didn’t check in, they didn’t count. But the reality is very different: hotels can significantly increase (and in some cases even double) their revenue by engaging guests who don’t book a room but use auxiliary services such as spas, restaurants, golf, or events. Loyalty doesn’t end when a guest leaves their room, but it extends to every interaction they have with the hotel.
In fact, according to our own data, one in five guest profiles never includes a room reservation. These guests still engage heavily with the brand, whether dining in restaurants, booking spa treatments, playing golf, or attending events. Despite their significant spending, they remain invisible in the Property Management System. This gap goes beyond a missed check-in; it masks a large portion of guest value and loyalty that hotels rarely see. Understanding these interactions is essential if hospitality leaders want to rethink how they approach loyalty, marketing, and revenue.
So why hasn’t the industry recognized this major revenue opportunity before? The answer is clear: data silos across hotel operations. Restaurants operate on one system, spas on another, and golf, ticketing, and events on separate platforms. The PMS contains only room-stay related data. When these systems don’t communicate, guest value becomes distorted. A frequent restaurant visitor may be treated as a first-time guest simply because they’ve never booked a room. A spa regular may receive generic marketing emails because their spend isn’t reflected in loyalty scoring.
Only around half of guest profiles include both a room stay and interactions at an outlet such as a restaurant or spa. Meanwhile, 28% reflect room-only activity, and up to 22% belong to guests who engage exclusively through venues management tools, never appearing in the hotel’s PMS. The consequences are significant. Frequent restaurant or spa visitors may be treated like first-time guests, marketing teams struggle to measure campaigns that drive venue revenue, and loyalty programs overlook high-value guests who engage beyond overnight stays. These gaps weaken personalization and limit hotels’ ability to build lasting relationships.
At the heart of this problem is a mindset barrier. The hospitality industry has historically been slow to adopt new technologies, and many core systems remain outdated, unable to connect data across operations. CRMs were introduced, then CDPs, but middleware, the infrastructure that ensures clean, synchronized, 2-way data flow, has often been overlooked. Without these connections, personalization and loyalty initiatives struggle to deliver on their promise because of incomplete information, and fragmentation becomes the norm rather than the exception.
This limitation is most visible in traditional loyalty programs, which still focus on rewarding overnight stays. Points accumulate based on room revenue, leaving out guests who spend thousands annually in dining, wellness, or events. Yet these are often the hotel’s most loyal patrons, engaging repeatedly with the brand across multiple touchpoints. True loyalty is not justabout points for room stays: it is about recognition and knowing if a guest prefers still water over sparkling, remembering dietary preferences, tailoring communication based on actual behavior rather than assumptions. Without a unified view of the guest, this kind of recognition simply isn’t scalable.
The same challenge also extends to guests who book through OTAs. Many consistently choose the same brand for convenience, yet their engagement beyond the room remains hidden. When hotel systems capture venue activity alongside room stays, these “OTA guests” are revealed as highly engaged brand loyalists, dining, using the spa, attending events, and returning frequently. The issue is not a lack of loyalty but limited visibility.
The core issue is not whether hotels can increase revenue through loyalty, but understanding precisely where loyalty begins and ends and, importantly, to whom it applies. Mapping the full guest journey – from room reservations to dining, spa visits, golf, or event attendance- is key for hotels to capture the true value of every guest. Only by integrating all touchpoints can properties recognize real loyalty, personalize experiences effectively, maximize revenue, and turn every interaction into a lasting and profitable relationship. In short, the opportunity is clearand hotels that see beyond the room are the ones that will truly win in both loyalty and profitability.
