Why the words matter before the numbers do
A hotel contract is written in the hotel's vocabulary, and the hotel has signed thousands of them. The organizer has signed a few. Almost every expensive surprise in event lodging comes from a word that meant one thing to the person who read it and another to the person who wrote it: a threshold measured in a way the organizer did not expect, a cutoff date that did something other than close the block, a rate that was not the rate the attendee saw. The arithmetic in these contracts is simple. The definitions are where the money hides.
The same is true on the revenue side. Rebate, commission and revenue share get used interchangeably in meetings, and they describe three different flows of money from three different parties with three different sets of obligations. An organizer who can tell them apart negotiates a better deal and, more importantly, knows which questions to ask a partner who is offering one. The sections below define each term once, in plain language, and say what it costs when it is misread. Where a term has its own post, the cluster at the end of the page goes deeper.
The block itself: room block, group rate, courtesy block, minimum and cutoff
A room block is a set of rooms a hotel holds out of general sale for an event's attendees, at an agreed rate, for a defined window. The organizer does not buy the rooms. Attendees book them directly with the hotel, usually under a code or a link, and the hotel reports back how many were taken. What makes a block a block is the hold: rooms the hotel will not sell to anyone else until a date you both agree. A group rate, by contrast, is only a price. The hotel agrees to charge attendees a negotiated rate while rooms last, with no hold and no guarantee in either direction. The difference matters because a block usually carries a guarantee from the organizer and a group rate usually does not.
A courtesy block is a block without the guarantee. The hotel holds a small number of rooms, typically for a shorter window, and releases whatever is unbooked at the cutoff with no penalty to the organizer. It is what hotels offer when the event is small, the dates are soft, or the relationship is new, and it is the right ask for most first-year and small events. A hotel block minimum is the other end of that conversation: the smallest number of rooms a property will hold under a contract at all, below which it will offer a courtesy block or a group rate instead. The cutoff date is the day the hold ends. On that day unbooked rooms go back into general sale, the code usually stops working, and attendees who book afterward are booking on the open market even if they stay at the same hotel. A cutoff is not the end of the organizer's lodging problem. It is the start of the part of the problem the block was never going to solve.
The guarantee: attrition, threshold, pickup, resell credit and the wash clause
Attrition is the penalty an organizer pays for filling less of a contracted block than it promised. The promise is the threshold, written as a share of the block, and the shortfall is the gap between the rooms actually booked and that threshold. Pickup is the count of rooms actually booked out of the block, and the way pickup is measured is the single most consequential definition in the contract. Measured cumulatively across the whole block, a strong Saturday can cover a weak Thursday. Measured night by night, every soft night is charged on its own. The two readings can produce very different bills from the same attendees, so the phrase to find in the contract is the one that says how the hotel counts.
Several related terms shape what the bill becomes. A resell credit means rooms the hotel manages to sell to other guests after the cutoff are credited against the organizer's shortfall, which is only fair and is not always offered. A wash clause, also called a reduction or slippage schedule, is the right to shrink the block by a stated amount at stated dates before the event without penalty, with the attrition threshold recalculating off the reduced number. It is worth more than any rate discount, because it turns a forecast into something the organizer can correct. Cancellation is a separate penalty on a separate schedule for calling the block or the event off, keyed to how much notice is given; it is not a cap on attrition and attrition is not a cap on it. A force majeure clause excuses performance for events outside anyone's control, and it governs neither penalty unless the contract says so.
The money: rebate, commission, revenue share and the rate the attendee sees
A rebate is money the hotel pays back to the organizer, after the event, on rooms booked inside the block. It is written into the contract as a fixed amount per room-night or a share of room revenue, it is paid by the hotel, and it depends entirely on the block being used. A commission is money a property pays to whichever channel delivered the guest. Properties already pay one, generally in the 15-20% range, to search engines, listing sites and booking platforms, on bookings the organizer never sees. It is the standard cost of being found, and it exists whether or not an event is involved.
A revenue share for events is a portion of that existing commission redirected to the organizer whose dates caused the trip. The attendee pays the property's own rate; nothing is added to fund the share, because the money was already leaving the property for a channel. That is the test of an honest arrangement: the rate on the event's page should be the rate the property publishes, and a partner that marks attendees up to fund the organizer's share should be dropped. Two more phrases belong here. Rate parity is the expectation that the same room costs the same on every channel, which is why a block rate that beats the public rate is a genuine concession and one that merely matches it is not. Merchant of record is whoever takes the attendee's money for the room and therefore owns the refund, the dispute and the phone call. In a block it is the hotel; in a revenue share it is the booking partner; in a travel package it becomes the organizer, which is the main reason packages cost more than they look.
Outside the block: open market, outside bookings, overflow and the sold-out block
The open market is every room an attendee can book that is not held under the event's contract: the same hotel after the cutoff, the hotel across the street, a rental, a campground, a spare room. Most of an event's lodging money moves there. At a sold-out date only about 31% of lodging money goes to properties inside the block, so the open market is not the exception to the block. It is the majority the block sits beside. Outside bookings are the attendees who stay in a contracted hotel but booked through a listing site or the hotel's own site rather than the code, and whether they count toward pickup depends on the contract and on the hotel's willingness to audit its own reservations against the attendee list. It is worth asking for, and it is worth writing down.
A sold-out block is the phrase that sounds like success and describes a shortage. It means the hold filled before the cutoff, which usually means the block was sized below the demand, and it leaves every attendee who comes after with no answer from the organizer. Overflow is the lodging arranged for those attendees: a second contracted hotel, a courtesy hold nearby, or a bookable list on the event's own pages. The honest version of a lodging plan treats the block as one tool for one part of the audience and the open market as the place the rest of them were always going to go, and gives that majority a real answer on the pages they use.
Where the attendee decides: lodging page, confirmation surfaces and the final 30 days
The lodging page is the where-to-stay page on the event's site, and the term covers everything from a paragraph with the hotel's phone number to a live list of bookable places for the dates. The confirmation page is the screen an attendee lands on after buying a ticket, and it is the highest-intent moment the organizer owns: the attendee has just committed to the dates and has not yet decided where to sleep. The confirmation email is read twice, once on receipt and once when the attendee plans the trip, and the second read is the one that matters for lodging. Reminder and follow-up emails extend the same idea to later weeks. A single lodging link, rather than a list of hotels to research, is what organizers mean when they talk about reducing the planning burden on attendees.
The final 30 days is the window where most of this happens. Roughly 70% of lodging money is committed inside the last 30 days before the dates, which is after most blocks have reached their cutoff and after most packages were priced. Timing the travel offer means placing the lodging answer on the surfaces that fire in that window, including the week-of reminder, rather than only at on-sale. The week-of window is the last of those surfaces and the one most organizers leave empty. Attendees who decide there are not late. They are typical, and a lodging plan that is absent from that window is absent for most of its audience.
Policies and roles: stay-to-play, housing bureau, housing desk, selling versus enabling
Stay-to-play is a tournament housing policy that requires travelling teams to book through the event's designated lodging provider, usually at designated hotels, as a condition of entry. It exists to make the block fill and the rebate pay, and families notice. A housing bureau is a third party that manages a conference's blocks across several hotels, takes the attendee reservations, and often earns from the hotels for doing so. A housing desk is the in-house version: the staff who answer the where-should-we-stay question, maintain the hotel list, and handle the changes. Each of these takes the lodging decision partly out of the attendee's hands, and each carries a cost in staff, obligation, or goodwill that the organizer should price before choosing it.
Selling travel means the organizer takes the attendee's money for the room and becomes the merchant of record for a stay it does not operate, as in a ticket-and-hotel package. Enabling travel means the organizer puts real, bookable options on the surfaces where attendees decide, a partner carries the booking and the support, and the organizer earns a share of the commission the property already pays. A lodging partner is the company that provides the enabling: the inventory, the booking, the fulfilment and the reporting. A performance-based partnership is one in which that partner earns only when a booking happens, which aligns the partner's incentive with the organizer's. These are the roles the rest of the vocabulary serves, and the choice between them is the real decision underneath every contract term above.
Reading the contract with the vocabulary in hand
With the terms defined, a hotel contract reads in a different order. The rate at the top is the least variable number on the page and the one the organizer can compare at a glance. The attrition threshold, the pickup measurement, the cutoff and the resell credit decide what the block costs when attendance disappoints, which is the only case worth pricing. The wash clause decides whether the organizer can correct the forecast. The cancellation schedule and its step-up dates decide what the bad year costs. The rebate decides what the good year pays back. Read in that order, two bids that look close on rate can turn out to be nowhere near each other on risk.
The vocabulary also settles the meeting after the contract. A block is for the attendees who want the organizer's hotel at the organizer's rate before the cutoff, and that is a real but minority group. The open market, the confirmation surfaces and the final 30 days are where the rest of the audience decides, and the terms for earning there are commission, revenue share and enabling rather than threshold, attrition and pickup. An organizer who holds both sets of words can size a block honestly, decline a guarantee it does not need, and put a bookable answer in front of the attendees the block was never going to reach.
