A booking for a peak week cancels on a Tuesday. It is the most valuable week of the year and it is now empty.
The owner remembers that several people asked about that week. She does not know who, when, or what they wanted, because those conversations happened over four months in three different channels.
She posts about the availability and waits. It goes unfilled. Eleven people would have taken it and none of them were contacted, because no list existed.
Step 1: build the list as enquiries arrive
Every person who asked about a period that was unavailable, recorded with what they wanted. This is the entire mechanism and it has to happen months before the cancellation.
Step 2: record specifics, not names
Dates wanted, flexibility, numbers, requirements and how quickly they could commit. A list of names without details cannot be matched to a gap.
Step 3: ask about flexibility at the point of enquiry
Somebody who could take any week in August is far more useful than somebody who needs one specific week, and both should be recorded differently.
Step 4: ask whether they want to be contacted
Explicitly, at the time. This makes the later message welcome rather than intrusive and it removes any awkwardness about holding the record.
Step 5: contact everybody at once
Not one at a time. The opportunity has a short life and sequential contact wastes it, which is the single most common failure with a waiting list.
Step 6: make a specific offer with a deadline
These exact dates, this price, hold until tomorrow at midday. Specificity and urgency are what convert a short notice slot.
Step 7: keep the list in date order
So that a gap on particular dates immediately identifies who to contact. A list organised by when somebody enquired is nearly useless.
Step 8: contact previous customers first
People who have been before need less persuading, decide faster and are more likely to commit at short notice.
Step 9: have the terms ready for a short notice booking
Deposit, cancellation and payment, which will be stricter for a booking taken eleven days out, and which should be prepared rather than improvised, as in deposit and cancellation questions in peak season.
Step 10: keep the list current
Remove people who booked elsewhere and ask periodically whether they are still interested. A stale list produces a poor response rate and looks careless.
Step 11: use it for the off season too
Quiet periods can be filled from the same list with a different offer, and the list is doing nothing for most of the year.
Step 12: build it in the quiet months
Off season enquiries are exactly the people who belong on it, and the quiet months are when the list should be growing fastest.
Step 13: borrow the mechanics from other waiting lists
The same problem of holding people through a long wait appears in nurseries schools and the waiting list question.
Step 14: let something build and work the list for you
An assistant that records every unavailable enquiry with its dates and flexibility, and contacts the matching people within minutes of a cancellation, fills a peak gap on the afternoon it appears. The same mechanism is described in how dental practices fill cancellations with a chatbot, and the wider preparation in preparing for a peak you cannot staff for. See features, start at try, and the sector view sits under small business.
