Question
You want to make sure two bookings can't be scheduled into the same party room at the same time.
Solution
ROLLER prevents double-booking automatically when your resources, buffer time and schedules are set up correctly. A party room is a resource, and once a booking takes a resource for a time slot, that slot is no longer available to other bookings.
Set the resource booking rule
When you create a resource, choose the booking rule that matches how the space is used. From Venue Manager, go to Settings > Resources.
Single booking gives one booking exclusive use of the resource for the time slot, no matter its capacity. Use this for party rooms.
Multiple bookings lets several guests book the resource until it reaches capacity. Use this for shared spaces like a general play area.
Add buffer time between bookings
Buffer time adds a gap between bookings on the same resource so parties can't be booked back to back without time to reset the room. You set buffer time on the party package: from Venue Manager, go to Products > All products, select the party package, then under Party package details select Edit program and turn on Add buffer time.
Check availability before you book
When a resource is already taken for a time slot, it appears grayed out and can't be selected. To see the full picture for a day, from Venue Manager go to Bookings > Daily capacity to view how many guests are booked against each resource and where space remains.
The calendar shows a booking's total tickets at its first session time, so a slot can look busier than it is. Use the Daily capacity page for an accurate view of what's actually available.
