The IdealStay Standard
Who gets Christmas? A fairness standard for co-ownership scheduling
Every co-ownership deal is sold on the home. Almost every co-ownership deal that goes badly, goes badly on the calendar. This is an independent look at how the major platforms actually allocate time, what separates a fair system from a merely functional one, and the five tests we hold ourselves to.

The question nobody asks until it is too late
Buyers evaluating a co-owned home ask about price, about the LLC, about resale, about who pays for the roof. They rarely ask the question that will actually determine whether they love the arrangement in year three: when eight families want the same week in December, what happens?
Pacaso’s chief executive has said the objection he hears first is some version of “isn’t everyone going to want the Fourth of July,” and his answer is that in practice owners diverge more than people expect. That is probably true and it is also not a scheduling system. Divergent preferences are a happy accident. A fairness mechanism is a design decision, and it is the one piece of the model that most buyers never inspect before signing.
We are licensed brokers who represent buyers across every provider in this market. We have a commercial relationship with several of the companies discussed here, which is disclosed at the end of this paper. That is precisely why we think the fairness mechanism should be written down, compared in public, and held to a standard that does not belong to any single platform.
Three design families
Nearly every scheduling system in shared ownership descends from one of three approaches. They are not equally good, but none is simply wrong, and the differences matter more than the marketing suggests.
1. Fixed allocation
The oldest model, inherited from the timeshare era: you own week 27, forever. Its virtue is that it cannot be gamed. Its defect is that it is not really ownership of a home, it is ownership of a slot, and it converts a vacation home into an appointment. Modern co-ownership has almost entirely abandoned it, and the abandonment is one of the honest differences between co-ownership and timeshare.
2. Rotating priority selection
Owners choose their weeks for the coming year in an order that rotates annually, so the family who picked first this year picks last next year. Ancana operates a version of this: co-owners select the following year’s weeks during a defined annual window, and the selection position rotates each year so that every owner eventually holds first choice, with booking otherwise available from three days to two years out.
The strength here is that the fairness is legible. You can hold the rule in your head, explain it to your spouse, and audit it yourself. The weakness is rigidity: it asks people to know in November what they will want the following August, and it rewards planners over the spontaneous.
3. Dynamic booking with entitlement gating
The newest family, and the one Pacaso has pushed furthest. There is no ranking order and no annual draft. Owners book in real time against live availability, and fairness is enforced by rules that sit underneath the calendar rather than by a queue.
The published mechanics are worth stating precisely, because they are the most detailed public description of a fairness engine in this industry. Booking runs on a rolling window from two days to twenty four months ahead. Stays come in two kinds: advance stays, planned ahead, and short notice stays, booked two to thirty days out for fully sold homes. An owner of a one eighth share may hold up to four advance stays at a time, one of which may fall on a designated special date, and may take unlimited short notice stays. Special dates are a defined set: federal holidays plus local events chosen per home, so Sundance is a special date for a Park City home. Each share entitles the owner to hold one special date at a time, and once a booked special date falls inside the short notice window it stops counting against that entitlement, freeing the owner to claim another. Stays run two to fourteen nights, and back to back stays are not permitted.
The load bearing rule is the peak season gate: every owner gets the opportunity to book at least one peak season stay before any owner may book a second. That single sentence is the difference between a booking app and a fairness system. Without it, dynamic booking is a race, and races reward whoever is most online.
Ember describes a comparable commitment in its own app, stating that prime dates are distributed equitably and that no single owner can dominate the calendar, with equal access to peak periods and holidays guaranteed. The published detail is thinner than Pacaso’s, which is itself a data point: the depth of disclosure varies enormously across this industry, and buyers should read that variance as information.
The five tests
Design families are a taxonomy, not a verdict. What follows is our attempt at the verdict: five questions we believe any co-ownership scheduling system should be able to answer in writing, before you sign anything. They apply equally to a Pacaso home, an Ember home, and eight friends buying a cabin together with a lawyer and a spreadsheet.
Test one: Is peak time gated, not raced?
The system must guarantee that every owner secures peak access before any owner secures a second helping. Whether that guarantee is delivered by a rotation, a gate, or an allocation of credits matters far less than whether it exists. If the answer is “first come, first served,” the honest translation is that the most available person wins, and availability is not a form of ownership anyone paid for.
Test two: Does the rule survive a bad year?
Fair systems are easy when everyone is agreeable. Ask what happens when two owners want the same holiday and neither will move. A real mechanism produces an answer without a negotiation. If resolving the collision requires a group conversation, the mechanism is a suggestion, and suggestions fail in exactly the years when families are least flexible.
Test three: Can an ordinary owner audit it?
An owner should be able to look at the calendar and independently verify that the rules were followed. Algorithms that are fair but opaque still corrode trust, because the co-owner who loses a date cannot tell whether the system worked or whether someone else was favored. Publishing the rule is not a courtesy. It is the mechanism by which the rule earns its authority.
Test four: Is spontaneity preserved?
A vacation home you can only use by planning eleven months out is a scheduling obligation with a view. Any decent system needs a release valve: unclaimed nights should open progressively as the date approaches, and using them should not cost an owner their future entitlement. Pacaso’s short notice stays are the clearest published example, and the fact that they are unlimited for a one eighth owner is, in our reading, the most underrated feature in the category.
Test five: Who is the calendar actually serving?
This is the test that separates lifestyle co-ownership from investment products wearing its clothes. If the manager can place paying guests into the home, then every unclaimed owner night has a revenue value, and the operator’s incentives are no longer identical to the owners’. Pacaso resolves this bluntly by not renting its homes at all. Other platforms, including Ember through its Flex option and Fraxioned and Ancana in their own forms, do allow owners to rent unused time, which many buyers reasonably want. Neither answer is wrong. What is wrong is not knowing which one you bought. Ask whether rental time competes with owner time, who decides, and who is paid.
What Ideal Location commits to
We do not yet operate a scheduling platform, and we are not going to pretend otherwise in a paper about transparency. What we can commit to now is how we will behave in this market, and what any home carrying our name will be held to.
First, we will publish the scheduling rules of any home we represent before a buyer is asked for a decision, in plain language, including the parts that are unflattering. Second, any residence Ideal Location itself brings to market will satisfy all five tests above, with the rules recorded in the ownership agreement rather than living in a product roadmap. Third, where we manage a home in which we retain a share, our own nights will be governed by the same gate as everyone else’s, and any rental of our nights will be disclosed in writing to the other owners. An operator who exempts itself from its own fairness rule does not have a fairness rule.
We think the eventual right answer for a small owner group is a demand weighted allocation: every share receives an identical annual budget of stay credits, and nights are priced in credits according to demand, so that a Christmas week costs more of your budget than a Tuesday in October. It preserves choice, it makes the tradeoff explicit, and it is auditable on a single page. We have not implemented it, we do not claim it is proven, and we would rather say that plainly than sell a diagram as a product.
The gap nobody has filled
One finding from building this paper is worth stating on its own. We maintain a database of more than four hundred vendors serving the short term rental and vacation home industry across eighteen categories, from property management systems to revenue tools to compliance platforms. There is no category for co-ownership scheduling, because there are effectively no independent vendors in it. Every fairness engine described above is proprietary to the platform that sells the shares.
That means the roughly comparable systems available to an independent group of eight friends buying a home together are: a shared calendar, a group text, and goodwill. The enterprise property management platforms with genuine owner portals and trust accounting, the Escapias and Streamlines and Barefoots of the world, were built to serve rental managers reporting income to owners, not to arbitrate usage between them. It is a real hole in the tooling of this industry, and we suspect it gets filled within a few years, either by a platform unbundling its own engine or by someone building it independently. We are watching it closely.
How to use this paper
If you are evaluating a co-owned home, take the five tests to whoever is selling it and ask for the answers in writing. If you are buying with people you know, adopt the tests as the outline of your usage agreement before anyone signs, because the cheapest time to resolve a Christmas dispute is several years before it happens. If you are a provider and you think we have described your system incorrectly, tell us and we will correct it; this document carries a date and an edition number for exactly that reason.
