Waiting list
When a date or a course sells out the form becomes a queue, and a place that comes free is held for the next person in line.
A sold-out event is a page that still has people on it. The waiting list is what you do with them.
A queue for each date
When a date sells out, the booking form offers a waiting list for that date instead. The visitor leaves their name and how many places they want, and keeps a position in the queue. A course or a pass that is full can be waited for as a whole.
One offer per place
Somebody cancels and the place is offered to the first person who can use it, by a private link, and to nobody else. Three cancellations tell three people, not the whole list. Two people are never sent the same seat, which is the mistake that turns a good gesture into an argument.
The place is held
An offer holds the place for 24 hours, and nobody else can buy it in that time. The link opens the booking form with the date already chosen and says how long is left, so the person offered a place does not arrive to find it gone.
An offer that runs out moves on to the next person. Whoever missed it stays in the queue, behind the people who have not had an offer yet.
A claim is an ordinary booking
Following the link makes a real booking: same form, same payment, same ticket, same confirmation. Nothing about it is a special case afterwards.
The list can be turned off for the events where it does not fit. In the Pro and Elite plans.
