Chobble Tickets sells timed entry by giving each entry time its own listing, such as "Entry at 10am" and "Entry at 2pm". Visitors choose a date and a time, each time slot has its own number of places, and a group can cap the total for the whole day.
Each time slot is a daily listing, so the visitor picks the date from a calendar and the slot's places are counted for that date on its own. Bookable days limit each slot to the days it runs. Four slots that run every Sunday are four listings, not a new listing for each Sunday.
The slots go into one group. Hiding each slot from the public list leaves the group as the one thing visitors see, and they choose their time inside it.
A farm park takes 60 visitors in each of three entry slots, at 10am, 12pm and 2pm, but only 150 people on site in a day. It creates three daily listings with 60 places each and puts them in a group with a maximum of 150. On a busy Saturday, once 150 tickets have been sold across the three slots, all three stop selling, even if one slot still has places of its own.
At the gate, staff scan each ticket with a phone, using the scanner for the slot that is arriving. If a 2pm ticket is scanned at the 10am slot, the scanner asks staff to confirm before checking the visitor in.
Opening the checkout does not hold a slot. Places are counted when the payment is confirmed, and if two payments race for the last place in a slot, the later one is refunded automatically. Registration deadlines can stop bookings a set number of days ahead.
There is no separate time field, so the slot's time is written in its name. Each slot is set up as its own listing, which takes longer for an attraction with many short slots across the day. Chobble Tickets does not sell seats, and does not run tills or kiosks for walk-up sales, though staff can add walk-ups by hand.
The attractions and days out page covers farm parks, museums and grottos in more detail.
