The demand is already there. You're just not capturing it.
Here's an uncomfortable number: 2,200 people a month search Google for “hotel day pass.” ResortPass, a company whose entire business is reselling access to hotel amenities, pulls over 20,000 monthly brand searches in the US alone.
Those are guests actively trying to give hotels money for things that aren't rooms. Most of that demand gets intermediated by someone else, or it evaporates, because there's no way to buy directly.
Now look inside your own building. The spa at 2pm on a Tuesday. The meeting room nobody booked this week. Cabanas on a Wednesday. Parking spaces sitting empty. Restaurant covers at 6pm. These are perishable assets with near-zero marginal cost — the revenue on an unsold spa hour isn't deferred, it's gone.
Ancillary revenue isn't a new product line. It's the money already inside your building that has no checkout.
What you can sell
Most hotels underestimate their own inventory. This is the list we work through in a typical discovery session:
| Category | Sellable inventory | Why it converts |
|---|---|---|
| Wellness | Spa treatments, day spa access, massage, sauna, gym day passes, fitness classes | High margin, highly perishable, strong pre-arrival intent |
| Pool & outdoor | Day passes, cabana rentals, poolside service, beach equipment | Proven consumer demand — this is the “hotel day pass” market |
| Space | Meeting rooms, event space, coworking day desks, private dining rooms | Idle midweek capacity; sells to locals as well as guests |
| Parking & transport | Parking, valet, EV charging, airport transfers, bike and car hire | The easiest first upsell — near-universal need, zero friction |
| Food & beverage | Restaurant reservations, chef's table, room service packages, wine tastings, breakfast add-ons | Highest repeat-purchase rate during a stay |
| Rooms & stay | Upgrades, early check-in, late checkout, connecting rooms, pet fees | Traditional upsell — the 10% most hotels already do |
| Experiences | Hotel-created tours, seasonal events, family activities, wellness programmes, packages | Differentiation; can't be price-compared against competitors |
| Local partners | Restaurants, attractions, harbour cruises, museums, retail, transport, services | Extends your offering without any capital investment — see local partner marketplace |
The first three rows are usually where a pilot starts, because the inventory already exists and nobody is selling it.
Upselling, done at every moment — not just at check-in
Front-desk upselling works, and it's also the narrowest possible version of the idea. It happens once, to one person, in a thirty-second window, when the guest is tired and holding a suitcase.
An upsell programme that actually moves numbers runs across the whole relationship:
At booking — attach experiences and services to the reservation while the guest is still in planning mode and their budget is unspent.
Pre-arrival — the anticipation window. Consistently the highest-converting moment for ancillary sales, and the one most hotels use only for a confirmation email.
At check-in — upgrades and add-ons, now with your staff seeing what the guest already bought instead of guessing.
In-stay — the 2pm free afternoon. QR codes, in-room, mobile, and the AI concierge all selling from live inventory.
Post-checkout — gift cards, rebooking, and the experiences they didn't get to.
Automated where it should be, human where it matters. AI handles the timing and the relevance at scale; your team handles the judgment calls and the high-value conversations. Both sell from the same inventory, and both see what the other did.
From RevPAR to TRevPAR
Most hotels are still managed on RevPAR — revenue per available room. It's a rooms metric, and it makes everything that isn't a room invisible to the people running the property.
TRevPAR — total revenue per available room — counts everything: rooms, F&B, spa, parking, experiences, partner commission. The moment you measure it, two things become obvious. First, how much of your total revenue has never been managed or merchandised at all. Second, that ancillary revenue is the only lever that grows income without raising rates, adding rooms, or spending more on acquisition.
That's the strategic case. It's also why this page exists rather than a page about upgrades: read the full guide to increasing hotel revenue.
What the platform does
Turns any asset into bookable inventory — availability, pricing, rules and capacity for things your PMS was never designed to sell.
Sells across every guest touchpoint — booking engine, pre-arrival, in-room QR, mobile, concierge desk, front desk. One inventory, every surface.
Bundles rooms with everything else — a single cart and single payment for a room, a spa slot and a harbour cruise. Bundles resist price comparison in a way bare rooms never can.
Dynamic and rule-based pricing — discount the Tuesday spa slot, premium-price the Saturday cabana, all automatically.
Local partner inventory alongside your own — sell what you don't own, on your terms.
Reporting that shows TRevPAR, not just occupancy — revenue by asset, by channel, by moment in the guest journey.
Your brand end to end — white-label, no third-party marketplace between you and your guest.
Fits your existing stack
Works alongside your PMS, POS, spa and F&B systems, payments and CRM — reading availability, posting charges to the folio where appropriate, and keeping revenue reporting whole. Cloud-native, API-ready, white-label. Pilot properties typically go live in days, not quarters.
Frequently asked questions
- What is hotel ancillary revenue?
- Hotel ancillary revenue is income a hotel earns from anything other than room rates — spa treatments, parking, food and beverage, meeting space, day passes, experiences, and commission from local partners. Because most of these assets already exist and carry low marginal cost, ancillary revenue typically flows to the bottom line at a higher margin than incremental room revenue.
- What can hotels sell besides rooms?
- The common categories are wellness (spa, gym, day passes), pool and outdoor (cabanas, day passes), space (meeting rooms, event space, day desks), parking and transport, food and beverage, room-related upgrades, hotel-created experiences, and offerings from local partners such as restaurants, tours and attractions.
- What's the difference between upselling and ancillary revenue?
- Upselling means increasing the value of an existing purchase — a room upgrade, early check-in, a better view. Ancillary revenue is broader: it includes upselling but also everything sold outside the room booking, such as spa, parking, day passes, experiences and partner bookings. Upselling is one channel for generating ancillary revenue, not a synonym for it.
- How much ancillary revenue can a hotel generate?
- It varies widely by property type — a resort with a spa, pool and multiple outlets has far more sellable inventory than a limited-service urban hotel. The meaningful measure is TRevPAR (total revenue per available room) rather than a headline percentage, and the practical way to size it is a pilot that measures incremental revenue against your existing baseline.
- What is hotel upselling software?
- Hotel upselling software prompts and sells upgrades and add-ons at defined points in the guest journey — typically pre-arrival email, check-in, and in-stay. It differs from full ancillary revenue software in scope: upselling tools generally sell room-related products, while an ancillary revenue platform also sells non-room inventory and third-party partner offerings.
- Does this replace our PMS?
- No. It sits alongside your PMS and other operational systems, handling the inventory and commerce your PMS wasn't built for, and syncing bookings and charges back into the systems you already run.
