Two formats, two different trips
A hotel room and a rented house are not two prices for the same thing. They are answers to two different trips. A hotel suits a single traveller or a single family on a short stay, anyone who values free cancellation and loyalty points, and any group that wants to be physically together with the rest of the team, the wedding party or the delegation. It offers a front desk, a cleaned room, and no obligation to think about anything beyond check-in.
A house suits the group that wants to be together in a different sense: two or more families or a set of friends sharing a kitchen, a living room and a lower cost per bed. It suits longer stays, travellers with children or grandparents in tow, and anyone whose trip is the weekend rather than the event alone. It also suits the people your plan tends to forget, the volunteers, officials and vendor crews who arrive earliest, stay longest and are rarely offered anything.
The mistake is not choosing one format. It is assuming that the attendees who wanted the other one will adapt. They do not. The family that wanted a house does not book into the block because you only offered a block; it goes to a rental site and finds one. The organizer who offered a single format did not lose that booking to a competitor. They lost it to nobody, which is worse, because there was no reason to lose it at all.
The demand your block pickup cannot see
Every lodging report an organizer normally receives comes from a hotel, and it counts reservations made under the block code. A house rented by four families a mile from the venue appears in none of it. Neither does the family that took a rental because the block was full, nor the group that booked the same hotel through a booking site without the code. The reports say the block picked up a certain number of rooms, and everyone quietly treats that as the size of the event's lodging.
It is not. In one event market we measured, a single event produced about 550 room-nights, roughly 70% of the lodging money was committed inside the final 30 days, and about 31% of it went to properties inside a block that had already sold out. Nothing in that picture was visible to the organizer at the time. The block reported what the block held. The rest of the demand, houses included, went where it went and paid whoever it paid.
This is why the house share is consistently underestimated. Not because it is small, but because the only instrument most organizers own is calibrated to miss it. If you want to know how your attendees actually stay, the block pickup is the wrong place to look. The right places are the confirmation-page click, the lodging-page traffic, and the attendee survey, all of which see rentals and hotels alike.
Why groups take so long to book a house
Rentals are booked by groups, and groups do not book; they discuss. Four families on the same roster, six friends coming to the same festival, three couples attending one wedding: each of them has a thread somewhere with a name that made someone laugh, and each thread is stuck on the same problem. Nobody wants to book first. Book the hotel and you learn that evening everyone else is sharing a house. Book the house and two of the families drop out and you are covering the gap. Book anything before the schedule is published and you may have picked the wrong side of town.
Each family's decision to wait a little longer is reasonable on its own. Taken together, the group waits as a unit, and the properties that suited them best are taken by travellers who were not deciding by committee. There is a second, quieter reason for the stall: the phrase stay together papers over real differences in budget, party size, arrival time and what people actually want from a weekend. Nobody wants to be the one who says theirs is the smallest budget or the longest list of needs.
Once those differences are visible, stay together usually turns out to mean something gentler: be near each other and near the venue. That is far easier to deliver than one property for everyone, and it changes what the organizer's job is. The job is not to find the house. It is to give the thread something to start from, at the moment it is paying attention, so the first message is a link to real options rather than a blank screen.
What each format is judged on, and how to present it honestly
A family comparing houses looks at three things: how many it sleeps, whether there is a kitchen, and how long the drive is to the venue. A listing that shows those three answers is doing the comparison work for them; a listing that shows a hero photo and a nightly rate is not. Bedrooms and beds matter separately, because a house that sleeps ten in three bedrooms is a very different trip from one that sleeps ten in five. Drive time should be to your venue, not to the town centre, because the venue is the only place they are certain to go.
A hotel block should be pitched on its real strengths rather than on loyalty to the event. Its strengths are proximity to the people you came with, a cancellation policy a house rarely matches, breakfast, and the absence of a cleaning fee or a checkout list. A block described that way wins the attendees it suits. A block described as the official hotel, with an implied obligation, wins some of them and irritates the rest, and it does nothing at all for the family that was always going to rent.
Presenting both honestly also means not pretending one is cheaper in every case. A house is cheaper per bed for a group and often more expensive for a couple. A hotel is cheaper for two nights and dearer for five. Let the attendee do that arithmetic against their own trip. Your page's job is to make the arithmetic possible, which means the formats have to sit side by side rather than on two different sites.
Offering both without becoming a housing bureau
The reason organizers avoid offering rentals is not that they doubt the demand. It is that they picture the work: a coordinator fielding calls about which house is nearest, emailing rooming lists, refereeing a group that cannot agree. That is the housing-bureau version of the job, and it is the wrong version. The formats self-sort. Put houses and hotels on one lodging page, with the block at the top while it has rooms and the open market beneath it, and the house-seekers click houses, the hotel families click the block, and nobody phones anyone.
Then put that page, rather than the block link, in every place the attendee already looks: the confirmation page, the confirmation email, the reminder emails, the event site's navigation and the answer your box office gives on the phone. The confirmation page is the one screen every buyer sees, at the moment the trip becomes real and the group thread starts. A link to a page with real, nearby availability in both formats gives the thread something to paste. A thank-you and nothing else sends everyone off to search alone.
None of this requires the organizer to hold inventory, vet individual houses or take a booking. The properties are listed and booked through whoever already lists and books them; the event's contribution is putting the right formats in front of the right people at the right moment. That is a placement decision, not a staffing one, and it is why a small team with no housing coordinator can offer both formats where a large team with one often offers only the block.
Sizing the block when houses are part of the offer
Once you accept that a share of your attendees will rent regardless, the block should be sized for the hotel crowd rather than for the whole audience. That usually means a smaller block than the hotel proposes, which is a good outcome: a smaller block fills more safely past its attrition threshold, and the rooms you did not guarantee are rooms you cannot be billed for. If the hotel offers a courtesy block or a group rate without a guarantee, that is often the better fit for an event whose demand is genuinely split.
Read the contract for what counts as pickup before you assume the houses are costing you. Rentals never count toward a block, but attendees who book the same hotel outside the code sometimes can, if the contract lets you submit names for the hotel to match. And do not let a house offer on your lodging page become a reason for the hotel to argue that you diverted demand. You did not; the demand was always going to split. What the page changes is whether the house half books somewhere you chose, near the venue, through a channel that pays you.
Track the split each season. The ratio of block bookings to house bookings on your own lodging page is the single most useful number you can carry into next year's hotel negotiation, because it tells you how many rooms to guarantee and how much of the audience the block was never going to hold. It is a number the hotel does not have and cannot dispute, and it moves the conversation from what the hotel would like to sell to what your attendees actually book.
Where the money is on the house side
A room block, at its best, pays the hotel and protects your attendees' rate. It rarely pays the organizer, and when it does the arrangement is tied to the block's own pickup, which is the smaller half of the demand. The house side is different. Bookings that an event refers to lodging around its dates, hotels and rentals alike, typically pay a commission in the 15-20% range, with nothing to guarantee and nothing to pay up front, because the referral only earns when a reservation is made.
That arrangement fits the shape of rental demand better than a contract ever could. Houses are booked late, by groups, in the final weeks when the block has often closed and the demand is at its largest. A referral has no cutoff, no attrition and no ceiling, so it keeps working through exactly the window when the block has stopped. And because the house bookings were never going to appear in a hotel report, the referral is the only way the event ever sees them at all.
The result is a lodging plan that matches the demand's actual shape rather than the block's. The block holds the attendees it suits, on terms sized to that group. The lodging page carries everyone else, houses and hotels together, from the confirmation page onward. The event stops fielding the where-to-stay question by hand, stops losing the house half to nobody, and earns on the majority of its lodging instead of the sliver a block can count.
